Theoretical N2-, 02-, and Air-Broadened Halfwidths of Ozone Calculated by Quantum Fourier Transform Theory with Realistic Collision Dynamics.
Abstract
Collision broadened halfwidths of ozone are evaluated with nitrogen, oxygen, and air as the perturbing gases. It is important to consider more realistic collision dynamics in the calculations. By replacing the classical path trajectories by linear trajectories with constant velocities chosen to give the equations of motion exact to first order in time we develop the interruption function in terms of the actual distance of closest approach determined by the intermolecular potential and the velocity at this point. This improvement to the theory results in halfwidths which are in good agreement with experimental measurements. The temperature dependence of the halfwidth has been determined for 126 transactions for N2-broadening and for 10 transitions for 02-broadening. Comparison with experimental measurements is given.
