Abstract
A study of the detailed kinetics and particularly the CO2quenching of CO fourth positive emission from active nitrogen has yielded individual rate coefficients for the energy transfer from N2(a1Πg),v= 0, 1 and 2 to CO(A1Π),v= 0 - 4. These do not follow any simple pattern. At high CO concentrations, an additional population of CO(A1Π),v= 1 and 6 from high levels of N2(a1Πg) and (a'1u-) occurs via the intermediacy of CO(I1-).
