Abstract
The water vapor line broadening and shifting coefficients for the HDO-16 and HDO-17 lines in the 6400-7000 cm-1 spectral region induced by oxygen pressure are measured with a spectral resolution of 0.01 cm-1 at room temperature by a Fourier transform spectrometer. Measurements were carried out using Bruker IFS-125M Fourier spectrometer with a 60 cm multipath cell, with a path length of 1920 cm. The volume of the cell is 2.765 L. The absorption spectra of the HDO-16 and HDO-17 isotopologue were recorded at pressure of 23 mBar and oxygen pressures of 0, 171, 422 and 655 mBar. The difference in the broadening coefficients of the HDO-16 and HDO-17 absorption lines for the (101)–(000) band does not exceed 5%.
