Abstract
The parameters of a nonpolynomial analytical model γ (sur) are determined from the fitting of the known experimental data on the N2-, O2-, air-, and self-broadening coefficients of the ozone absorption lines. The model gives a finite value for the coefficients γ in asymptotic. The average accuracy of experimental data description is better than 3% for several thousand lines with quantum numbers up to J = 60. The results of the calculations based on the model suggested are compared to the results obtained using polynomial representations for the broadening coefficients.
