H2O self-broadening coefficients of rotation-vibration lines in the 15 500-16 000 cm-1 region

Line broadening coefficients of the Н2О-Н2О system were investigated in the region 15500 - 16000 cm-1 using a high resolution Fourier-transform spectrometer IFS-125M. The White type multipass absorption cell with a basic length of 60 cm was used. Least-square-fitting algorithm WXSPE was used to retr...

Description
Summary:Line broadening coefficients of the Н2О-Н2О system were investigated in the region 15500 - 16000 cm-1 using a high resolution Fourier-transform spectrometer IFS-125M. The White type multipass absorption cell with a basic length of 60 cm was used. Least-square-fitting algorithm WXSPE was used to retrieve of the spectroscopic parameters from measured spectral data set. Calculations of self-broadening are performed using a semi-empirical approach. This method is further developed by using anharmonic wavefunctions in the estimates of line profiles. This approach explicitly takes into account all scattering channels induced by collisions. Calculated data are in a good agreement with the measured ones. © (2015) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
