Efficient excitation transfer from N{sub 2}(A) and CO(a) to OH has been observed in a room-temperature flow reactor. The excitation-transfer rate constants for OH(A{sup 2}{Sigma}{sup +}) formation are (9.5 {plus minus} 1.9) {times} 10{sup {minus}11} and (4.0 {plus minus} 2.0) {times} 10{sup {minus}11} cm{sup 3} molecule{sup {minus}1} s{sup {minus}1} for N{sub 2}(A) and CO(a), respectively. These values suggest that excitation transfer makes the dominant contribution to the total quenching of N{sub 2}(A) and CO(a) by OH. The OH(A) molecules are formed with high rotational energy.
