Abstract:

Measurements are presented of rates of electronic quenching of COa, vO by several gases. A pump-and-probe technique is used COa is created by pumping the spin-forbidden a-X transition at 206 nm. Measured rate coefficients at room temperature are ksub QCO 5.7 - 1.2, ksub QNO 17 - 6, ksub QN2 1.4 - 0.6, ksub QO2 6 - 2, ksub QH2 2.6 - 1.0, ksub QH2O 33 - 12 in units of 10exp -11 cu cms.
