Paper Abstract

The measurements of half-width and shift of H2O absorption lines due to foreign gas pressure are interesting for studying the intermolecular interactions in gases as well as for application of spectroscopic data in atmospheric optics. The half-width and shift of H2O isolated absorption line of (nu) 1 + 3(nu) 3 vibration-rotation band were measured in the H2O-air and H2O-H2 mixtures at varying the temperature of gases from 290 to 400 K. The measurements have been carried out using the dual-channel photo-acoustic spectrometer with a frequency tunable ruby laser, providing the spectral resolution of 0.01 cm-1.
