摘要：

The technique of time resolved Fourier spectroscopy has been used to determine rate constants for the processes CO(υ)+CO 2→CO(υ-1)+CO2, where the vibrationally excited CO is created through electron irradiation of Ar/CO2 mixtures. The CO production mechanism, predominantly dissociative recombination of CO 2+, is found to produce CO excited to as much as υ=19. The CO(υ) deactivation rate constants are deduced from examination of the time histories of the vibrational population distribution. From a Stern-Volmer analysis, the residual quenching not due to CO2 is attributed entirely to CO(υ=0) relaxation of CO(υ) and radiative decay. Experimentally determined upper bounds for the CO(Δυ=1) transition probabilities for spontaneous emission have been obtained for levels 7-12. © 1979 American Institute of Physics.
