Measurement of CO(ν = 1) vibrational energy transfer rates using a frequency-doubled CO2 laser

Abstract

Laser-induced fluorescence studies of CO collisional relaxation have been carried out using the output of a frequency-doubled, pulsed CO2 laser as a direct source of CO(ν = 1) excitation. Energy transfer cross sections at 298 °K are reported for CO in collisions with He, Ar, H2, D2, N2, O2, Cl2, NO, CH4, CF4, and SF6. The D2–D2 self-relaxation rate was also obtained from the analysis of CO–D2 mixtures.
