Using a stabilized diode-laser spectrometer, we have studied the line profiles of water vapor near 7185.59 cm -1 . With low pressures of pure gas (≤1 Torr) in a White-type cell, we have deduced the line intensities using the Voigt profile. This study shows clear differences between experimental and

✦ Synopsis
A diode laser spectrometer has been used for high accuracy (\mathrm{H}_{2} \mathrm{O}) line profile measurements near (5475 \mathrm{~cm}^{-1}). Measured lineshapes have been least-squares fitted by Voigt profile with a floating Gaussian component. Gaussian component pressure dependence resulting from the Dicke narrowing effect is observed. Line intensities, self- and air-induced broadenings, and shifts of five water vapor lines are presented. (C) 1993 Academic Press, Inc.

High-resolution diode laser spectroscopy was applied to measure absolute line intensities in the 9.8-mm n 14 band of benzene 12 C 6 H 6 . A new data treatment had to be developed to derive single line parameters from the strongly overlapped lines. This procedure includes a self-deconvolution and an
Diode laser measurements of \(\mathrm{CO}_{2}\) absorption spectra have been made in the \(2270-2295 \mathrm{~cm}^{-1}\) spectral region at low pressure ( \(<25 \mathrm{mbar}\) ) and at temperatures up to \(800 \mathrm{~K}\). Line intensities of several parallel hot bands \((20013 \leftarrow 20003,1
Spectrally resolved measurements of water vapor absorption spectra near \(1.4 \mu \mathrm{m}\) have been performed with a tunable, distributed-feedback InGaAsP diode laser. A lineshape analysis was used to infer the collision-broadening coefficient of 11 rovibrational transitions in the \(\nu_{1}+\n
Using an external-cavity diode laser (ECDL) as the light source, we have observed the spectrum of CO 2 in the 1.5-m atmospheric window including the (30 0 1) I 4 (00 0 0) and (31 1 1) I 4 (01 1 0) I bands. Good signal-to-noise ratio allowed us to lock the frequency of our ECDL to the absorption line
High-resolution diode laser spectroscopy was applied to measure broadening coefficients in the 9.8-µm nu14 band of benzene, C6H6. Self-broadening was investigated at 295 and 344 K for 73 lines between 1017.31 and 1045.85 cm-1 with 9
