Description

The influence of molecular oxygen admixture on the vibrational distribution function (VDF) of CO molecules in a dc electric discharge in He : CO : O2 mixtures was studied. It was revealed that for O2 concentrations exceeding 10% of CO content the processes of VV' exchange between CO and O2 molecules led to essential deformation of the CO VDF shape for vibrational states near v = 20 and higher. The comparison of experimentally measured and theoretically calculated VDFs of CO gave us a chance to realize the verification of CO-O2 VV' rate constants proposed earlier.
