Abstract

Measurements and calculations of the oxygen pressure-induced shift coefficients for more than 100 water vapor absorption lines of the (000) - (011) and (000) - (110) bands have been performed. Experimental data on line shift coefficients were obtained from analysis of H₂O - O₂ room temperature absorption spectra at 11 different pressures of O₂ over the range 148.5 Torr to 3800.4 Torr, using a Fourier transform spectrometer with spectral resolution of 0.0007 cm^-1 and an optical pathlength of 84.05 m. Calculations of line shift coefficients were performed using the Anderson semiclassical impact theory.
