Communication: Vibrational relaxation of CO((1)Sigma) in collision with Ar(S-1) at temperatures relevant to the hypersonic flight regime

摘要

Vibrational energy relaxation (VER) of diatomics following collisions with the surrounding medium is an important elementary process for modeling high-temperature gas flow. VER is characterized by two parameters: the vibrational relaxation time tau(vib) and the state relaxation rates. Here the vibrational relaxation of CO(v = 0 1 transitions that are ignored in typical applications of the Landau-Teller framework. Published by AIP Publishing.
