Анализ и аналитическое представление коэффициентов уширения линий водяного пара давлением воздуха, азота, кислорода и углекислого газа для спектрального диапазона 380-26000 cm-=SUP=--1-=/SUP=-

Abstract

The analysis of the available experimental data on the H2O line broadening coefficients by air, nitrogen, oxygen and carbon dioxide in the spectral range 380 -26000 cm-1 is carried out. The analysis is based on the application of the analytical model g(sur), which depends on the fitting parameters. N = 4110, N = 757, N=658 and N=688 air, nitrogen, oxygen and carbon dioxide broadening coefficients derived from the fitted parameters agree with measurements with an average accuracy of 7.2%, 11.6%, 7.6% and 7.1%, respectively. In a simultaneous analysis of N = 5525 air, nitrogen and oxygen broadening coefficients an average accuracy is 9.2%. The parameters of the analytical model g(sur) may be recommended in the  calculations of H2O lines with rotational quantum numbers J <20, Ka < 15 for any vibrational band from the mentioned spectral range
