Abstract
Self-broadened and foreign-gas ($N_{2}$ and $O_{2}$) - broadened linewidths of $O_{3}$ at $300^{\circ} K$ for a wide range of quantum numbers J and $K_{-1}$, for both type A and type B bands, have been calculated using the recent formulation by Yamamoto and Aoki for asymmetric top molecules in the framework of Anderson-Tsao-Curnutte theory of line broadening. The computer program written for these calculations is quite general and can be used for linewidth computations for other asymmetric top molecules. The values for the quadrupole moment tensor elements of $O_{3}$ have been taken from Rothenberg and Schaefer III. Computed values for linewidths are in good agreement with all of the available experimental data on $O_{3}$ linewidths. Air-broadened linewidths of $O_{3}$ at $200^{\circ} K$ have also been calculated.
