摘要：

A new method for estimation of broadening coefficients of vibrational-rotational lines of asymmetric tops is presented. The method allows finding line widths on the basis of a few empiric data without complicated calculations. Based on the analysis of experimental data, the dependence of the average energy difference on vibrational quantum numbers is found. The approach has been tested by the example of calculation of line broadening of asymmetric tops H2O and HDO. Calculated parameters of line profiles were compared with experimental data in different absorption bands. © 2015, Pleiades Publishing, Ltd.
