HF autorelaxation in v= 1 and v= 2

Abstract

A more reliable form of the power scaling law (PSL) is used for the calculation of rotational energy transfer (RET) rate constants. Good fits of experimentally determined double resonance signals for the rotational autorelaxation of HF in different vibrational levels are achieved. The kinetic scheme also accounts for vibrational energy transfer and multiquantum (Δj≤ 6) rotational jumps. These improvements are of fundamental importance in modelling pure rotational lasing transitions in chemical lasers.
