Vibration-to-rotation energy transfer in hydrogen fluoride: Effects of the dipole-dipole and hydrogen-bond interactions

Abstract

The importance of the dipole‐dipole and hydrogen‐bond interactions in the vibration‐to‐rotation energy transfer in hydrogen fluoride molecules is investigated in the temperature range of 300 to 4000°K. The collision trajectory and collision time are evaluated for the over‐all potential energy constructed from the sum of the exponential (Morse‐type) and dipole‐dipole interaction functions. Good agreement between the present calculations and experiment is found over the entire temperature range.
