Paper Abstract

Measurements of the pressure shifts coefficients for H2O absorption lines have been performed in the 9403 - 9414 cm-1 spectral region with H2 , O2, Ar, Xe, Kr and air as foreign gases. The data on lines shifts coefficients have been obtained from analysis of the H2O-H2, H2O-O2, H2O-Ar, H2O-Xe H2O-Kr and H2O-Air absorption spectrum recorded at room temperature using Nd glass intracavity laser spectrometer with spectral resolution of 0.03 cm-1 and absorption sensitivity of 10-8 cm-1. The pressure of H2O was varied from 10 Torr to 20 Torr and the pressure of the buffer gases - from 0 to 1000 mbar. The values of the line shifts coefficients for 8 lines have been derived from the recorded spectra, they ranged from 0.009 cm-1/atm to 0.069 cm-1/atm. For each buffer gas a linear relationship of line shifts was measured.
