The vibrational relaxation of CO₂ isolated in solid argon

Abstract

For description of the vibrational relaxation of CO₂ molecules embedded in Ar matrix the model based on multiphonon transitions is applied. Rates for the VT and VV processes are determined from a fitting of simulated and experimental data. The calculations confirmed that radiative processes influence significantly the vibrational energy relaxation of CO₂ embedded in solid Ar, e.g., the determined rate for energy transfer between n₃ and n₂. mode is significantly lower than that predicted under assumption of the nonradiative relaxation
