| Popis: |
Water vapor line broadening and shifting coefficients by nitrogen pressure were studied in the 22300-22600 cm-1 spectral range (6ν1+ν3 and 7ν1 bands) using a high resolution Fourier-transform spectrometer IFS-125M. Measurements were performed using IFS-125M Fourier transform spectrometer with a spectral resolution of 0.1 cm-1 and optical path length of 24 m. The Doppler FWHM in this region is ~0.066 cm-1. Calculations of N2-broadening coefficients were performed using a semi-empirical approach developed by using anharmonic wavefunctions determined from variational nuclear motion calculations. In this variant all scattering channels induced by collisions are taken into account. |
