Abstract The vibrational level distribution of the CO(a {sup 3}II) produced in the title reaction was measured in a rapidly pumped discharge-flow reactor at a total pressure of {approximately}2 Torr and {approximately}297 K. The emission from the CO(a {sup 3}II,v{sup {prime}}{r_arrow}X {sup 1}{Sigma}{sup +}, v{sup {prime}{prime}}) Cameron bands, observed from the product CO(a) formed in the title reaction, was collected with a 2.2-m vacuum-ultraviolet spectrograph-monochromator utilizing both photographic and photoelectric techniques. For N{sub 2}(A,v{sup {prime}}{le}4) + CO(X,v{sup {prime}{prime}}=O) the authors obtain a CO(a,v{sup {prime}}) population ratio of 1.00:0.85 for v{sup {prime}} = 0 and 1, respectively. This branching ratio differs from previous results for N{sub 2}(A,v{sup {prime}}{ge}0) which did not correct for competing removal processes of the CO(a) state. In order to obtain these results it was necessary to measure the room temperature biomolecular rate constants, k{sub v}{sup {prime}}`s, for the CO(a,v{sup {prime}}=0 and 1) + CF{sub 4} reactions which were determined to be {le}5 x 10{sup {minus}14} cm{sup 3} molecule{sup {minus}1} s{sup {minus}1}. 31 refs., 1 tab.
