On the desymmetrization of the collision-induced roto-translational spectral profiles of pairs of freely rotating linear molecules

摘要

For the purpose of desymmetrizing classical, computed profiles, we use the Egelstaff time transformation for both the translational and the rotational collision-induced absorption profiles of pairs of linear molecules. For simplicity, we assume an isotropic interaction potential, so that the translational and rotational motions are not coupled. Comparison of the desymmetrized, classical profiles with quantum computations show a high degree of consistency, and seem to suggest a broader applicability of our approach, perhaps even to the important case of anisotropic interactions.
