Abstract:

Water vapor absorption spectra were recorded between 13300 and 13800 cm^–1 using a laser spectrophotometer employing a long-base cell (30 m) and alexandrite laser. Spectrum width of the emitted radiation was less then 0.005 cm^–1; optical path was 1200 m. Measurements were conducted at 10 Torr and the room temperature. The laser radiation wavelength was determined using an evacuated interferometer with the accuracy higher than 0.001 cm^–1. Measurements were made for 44 lines giving an addition to the spectrum previously reported by Mandin, Chevillard, Camy-Peyret, and Flaud [J. Mol. Spectrosc. 116, 167–190 (1986)]. Positions and intensities of spectral lines were determined by fit of the Voigt profile to the observed values.
