The influence of rotational changes on the quantum number scaling of vibrationally inelastic rate constants

摘要

A general formula is presented, based upon the energy corrected sudden scaling theory, which describes the variation of rotationally equilibrated vibrationhyphen;tohyphen;translation relaxation rates with initial vibrational state. The influence of each rotational quantum number change on the vibrational scaling is explicitly displayed. This result allows for a detailed investigation of the possible role of rotational transitions on the vibrational relaxation in HF and DF upon collisions with structureless particles. Application to the HFndash;HF system yields the separateVndash;TandVndash;Vrelaxation rates in different vibrational levels.
