Abstract

The numerical calculation of self-broadening coefficients, shifts (δ) or half-widths (γ) leads to more than 3500 values for δ and γ for a ro-vibrational band of (formula available in paper). In the present work the analytical models for half-widths (formula available in paper) of H2O molecule (self-broadening case) are presented and discussed R is the set of rotational quantum numbers for initial, and final, states for the transition (formula available in paper). The models (available in paper) depend on the adjustable parameters, which may be determined for a given set of experimental data for γ. The self-broadening coefficients, shifts (δ) and half-widths (γ), were calculated for the first 10 vibrational bands and for the high values of (formula available in paper) molecule. The Robert Bonamy scheme ¹ was used. For (formula available in paper) band the values of δ and γ were calculated for the temperature 300 less than or equal to T less than or equal to 850 K with the step 50 K. The calculated values were compared with those obtained in a number of experimental studies.
