Abstract

The semi-empirical method has been used to determine of room temperature self-broadened halfwidths of methyl cyanide and CO2-broadened halfwidths of methyl chloride. We obtained data approximately for 1500 rotation-vibration transitions. J-dependences of these colliding systems are different due to various absorber-perturber resonance effects. Results of calculations clearly demonstrate a very good agreement between observed and computed parameters for both absorbing molecules.
