Title: A new analysis of the OH radical spectrum from solar infrared
observations.
Authors: Melen, F.; Sauval, A. J.; Grevesse, N.; Farmer, C. B.;
Servais, Ch.; Delbouille, L.; Roland, G.
1995JMoSp.174..490M Altcode:
The solar spectrum offered the opportunity to discover OH lines with
high rotational quantum numbers, which do not appear on laboratory
spectra. On solar absorption spectra, the authors have identified
about 580 lines, among which about 400 were observed for the first
time. They belong to pure rotational transitions in the ground state
(υ = 0→3; J<SUB>max</SUB>″= 48.5), as well as to the (1-0), (2-1),
and (3-2) vibration-rotation bands (J<SUB>max</SUB>″= 32.5). Previous
pure rotation, vibration-rotation, and Λ-doubling data sets related
to the υ = 0 up to 3 levels were fitted simultaneously together with
this new set of data, in order to obtain a very complete and accurate
set of molecular constants for the X<SUP>2</SUP>Π ground state.

Title: Concentrations of hydrogen chloride and hydrogen fluoride
measured during the MAP/GLOBUS campaign of September 1983
Authors: Zander, R.; Roland, G.; Delbouille, L.; Sauval, A. J.;
Marché, P.; Karcher, F.; Amoudei, M.; Dufour, B.
1987P&SS...35..665Z Altcode:
Within the context of the MAP/GLOBUS campaign of September 1983,
several trace species have been observed by absorption spectroscopy
at the two ground stations of the Jungfraujoch, Switzerland (3580
m altitude) and the Observatoire de Haute-Provence, France (1905 m
altitude). The results obtained for HCl and for HF, expressed in terms
of mean integrated columns above these sites are: Jungfraujoch: (2.1 ±
0.2) E15 mol cm <SUP>-2</SUP> HCl (4.8 ± 0.2) E14 mol cm <SUP>-2</SUP>
HF Haute-Provence: (2.6 ± 0.2) E15 mol cm <SUP>-2</SUP> HCl. Taking
into account the difference in the altitude of the two stations,
the reported HC1 results are in agreement to within their respective
uncertainties. The integrated column density of HCl and HF above 11 km
altitude, deduced from airplane observations on 9 September 1983, are:
(1.65 ± 0.25) E15 mol cm <SUP>-2</SUP> HCl above 11 km (3.7 ± 1.7)
E14 mol cm <SUP>-2</SUP> HF above 10 km supporting satisfactorily the
ground measurements.

Title: The nickel spectrum in the infrared - Application to the
solar spectrum
Authors: Biemont, E.; Delbouille, L.; Roland, G.; Brault, J. W.
1986A&AS...65...21B Altcode:
The spectrum emitted from a nickel hollow cathode has been recorded
in the infrared region (1800 < σ < 9000 cm<SUP>-1</SUP>) with
the National Solar Observatory Fourier transform spectrometer. The
spectra have been used in order to identify many lines on new high
resolution solar spectra.

Title: Fourier transform spectrographs.
Authors: Delbouille, Luc
1986ESOC...24..119D Altcode: 1986vlt..work..119D
Fourier-transform spectrograph (FTS) configurations for the ESO
Very Large Telescope (VLT) are discussed. The advantages of FTSs
over grating spectrographs are reviewed, including large throughput,
minimum line distortion, photometric accuracy, wavelength calibration,
instrumental flexibility, and the 'multiplex' advantage; the application
of state-of-the-art array detectors to FTSs is also considered. A
scaled-up version of the FTS for the 4-m Mayall telescope at KPNO (Hall
et al., 1979), with a 2-m-focal-length collimator and 30-cm cat's-eye
retroreflectors, is briefly characterized. It is suggested that such
an FTS be evaluated as a preliminary design for the VLT instrument.

Title: Identification on chromium lines in the infrared solar spectrum
based on new interferometric measurements
Authors: Biemont, E.; Delbouille, L.; Roland, G.; Brault, J. W.
1985A&AS...61..185B Altcode:
High resolution spectra of chromium obtained by the interferometric
method show the presence of several hundreds of new lines in the
infrared region (1800 < V < 9000 cm<SUP>-1</SUP>). These spectra
have been used in order to proceed to the identification of many
weak lines on the high resolution solar spectra obtained recently by
Delbouille et al. (1981).

Title: An investigation of iron in the infrared solar spectrum based
on FTS laboratory measurements
Authors: Biemont, E.; Roland, G.; Delbouille, L.; Brault, J. W.
1985A&AS...61..107B Altcode:
The application of new high-resolution laboratory data for iron,
covering the region 1800 to 9000/cm, to the identification of many
weak lines on high signal-to-noise-ratio solar photospheric spectra,
is discussed. The spectra emitted by iron hollow cathodes with three
different carrier gases (He-Ne-Ar) are recorded with the Fourier
transform spectrometer on Kitt Peak. Comparisons between the spectra
of iron and the spectra of nickel and of chromium recorded with the
same carrier gas and between the iron spectrum and the KPNO solar
spectrum drawn at the same scale are considered. The results are
presented in tables.

Title: The Interest of Simultaneous Spectral and Spatial High
Resolution Spectroscopy in the Infrared
Authors: Delbouille, L.; Grevesse, N.; Sauval, A. J.
1985LNP...233..108D Altcode: 1985hrsp.proc..108D
Up to the present, small scale structures on the sun have mostly been
studied through observations made in the visible and ultraviolet. After
having recalled some of the main advantages of infrared observations,
the authors give a few samples of high spectral resolution/low noise
solar spectra now routinely obtained in this spectral range by using
Fourier transform spectrometers. The authors then show that such high
spectral resolution spectra could be obtained in short period of time
and for small scale solar structures, using a LEST type collector.

Title: Infrared bands of C2 in the solar photospheric spectrum
Authors: Brault, J. W.; Testerman, L.; Grevesse, N.; Sauval, A. J.;
Delbouille, L.; Roland, G.
1982A&A...108..201B Altcode:
Lines of the C<SUB>2</SUB> Phillips system have been successfully
searched for on new tracings of high resolution solar spectra. From a
rather large number of lines of the (0,0), (1,0), and (0, 1) bands,
we derive empirical values for the band oscillator strengths:
f<SUB>00</SUB> = 1.41 10<SUP>-3</SUP>, f<SUB>10</SUB> = 1.38
10<SUP>-3</SUP>, and f<SUB>01</SUB> = 1.12 10<SUP>-3</SUP>. These
solar f-values are discussed in section 3.1 and compared with recent
laboratory data. <P />For the Ballik-Ramsay system, only a few
unblended solar lines have been available, from which we deduced 0.6
10<SUP>-3</SUP> ≪ f<SUB>00</SUB> ≪ 1.2 10<SUP>-3</SUP>.

Title: f-values for Tb ii and a search for terbium in the solar
photosphere
Authors: Biemont, E.; Roland, G.; Delbouille, L.
1981SoPh...71..223B Altcode:
Oscillator strengths have been obtained for the first time for 12
transitions of Tb II. Solar implications based on these f-values and
on recent hyperfine structure data are discussed. More especially,
a detailed investigation of a weak absorption feature located around
λ 3658 is presented.

Title: Confirming the presence of hydrofluoric acid in the upper
stratosphere
Authors: Zander, R.; Roland, G.; Delbouille, L.
1977GeoRL...4..117Z Altcode:
Infrared solar observations made by balloon at 27.9 km altitude in April
1976, and from the ground station of the Jungfraujoch, Switzerland, in
October 1976, have confirmed the presence of hydrofluoric acid in the
upper stratosphere. An average value of (3.6 ± .7) × 10<SUP>-10</SUP>
ppv has been deduced for the concentration of HF above 27.9 km. The
comparison between the ground-and the balloon observations tends to
indicate that over 50% of the total atmospheric HF is located above
25 km altitude.

Title: High Resolution Spectra of the Sun
Authors: Delbouille, L.; Roland, G.
1969RSPTA.264..171D Altcode:
The University of Liege has operated, since 1958, a laboratory of solar
spectroscopy at the International Scientific Station of the Jungfraujoch
(Switzerland). During recent years, much effort has been devoted in two
main directions: (a) techniques of correction for the effects of the
instrumental function to obtain the best possible knowledge of central
intensities and profiles of photospheric lines; (b) increase of the
signal to noise ratio in the records in order to detect and measure
very faint absorption features. In addition, a balloon-borne equipment
is now under construction in Liege to observe, with maximum resolution,
the near infrared solar spectrum from an altitude of about 80 000 ft.

Title: Project to Map the Sky in the Infrared from an
E.S.R.O. Satellite
Authors: Delbouille, L.
1969RSPTA.264..319D Altcode:
One of the experiments installed in the TD 1 E.S.R.O. satellite
(expected launching date 1970), will be devoted to a mapping of the
sky in the lead sulphide region. The scanning will be obtained by
the motion of the satellite itself, so a relatively simple infrared
photometer will be used.

Title: A New Determination of the C^{12}/C^{13} Isotopic Abundance
Ratio in the Solar Photosphere
Authors: Herzberg, Luise; Delbouille, L.; Roland, G.
1967ApJ...147..697H Altcode:
The XX38743875 A region of the solar spectrum is re-examined for the
occurrence of lines of the 0-0 band of the ultraviolet system of the
C13N isotopic molecule. Although the well-known solar line X3874 341 A
is in excellent wavelength agreement with the P(58) line measured in
the laboratory, the P(57) line that should also occur in a window in
the solar spectrum is found to be absent. It is, therefore, concluded
that the wavelength agreement in the case of the F(58) line is spurious
and that no lines of C11N are observed. From this, a lower limit R 40
for the C12/C13 abundance ratio in the photosphere is obtained.
---------------------------------------------------------
Title: A New Determination of the 12C/13C Abundance Ratio in the
Solar Photosphere.
Authors: Delbouille, L.; Herzberg, Luise; Roland, G.
1966AJ.....71Q.383D Altcode:
There are at present in the literature two different values for
the photo spheric abundance ratio 12C/13C, derived from different
interpretations of the 3874 A region of the solar spectrum. This region,
as Greenstein, Richardson, and Schwarzschild (Publ. Astron. Soc. Pacific
62, 15, 1950) have suggested, is the only region where there are
suitable windows for the observation of lines of C13N [P(58), A3874.345A
and P(57), A3874.922 A of the 0,0 ultraviolet band]. Greenstein et
al. could not detect lines of 13CN, and from their absence and the
fact that in the windows the solar centinuum is approached within 3 %
derived a lower limit R=36 for the 12C/13C ratio. In contrast, Righini
(Liege Colloq. 1956, p. 265; Ric. Sci. Rev. 3, 145, 1963) obtained
R=104 on the assumption that the known weak 3874.358 A Zr+ line is
blended with the 13CN, P (58) line. Correction of a trivial error in
the equivalent width reduces his value to 10~, leaving a discrepancy
by more than a factor 10 between the results. We have re-examined the
question with solar spectra of higher resolution than obtained before,
and with new laboratory spectra kindly provided by A. E. Douglas. We
confirm the coincidence of the P (58) 13CN line with the Zr+ line at
x3874.358 A. However, near the predicted position of the P (57) line
A3874.923 A we find only one new line at A3874.99 A. The wavelength
difference of 0.07 A is too large for identification of this line as
13CN. We therefore conclude that the coincidence between the solar
line at 3874.358 A and the 13CN, P(58) line is spurious, and that even
the new high-resolution spectra do not show lines of 13CN. From this
we arrive at a lower limit R 40, essentially confirming the value of
Greenstein et al.
