Measurement of Quenching Rates of CO(a sup 3Pi, v=0) Using Laser Pump-and-Probe Technique
Abstract
Measurements are presented of rates of electronic quenching of CO(a, v=O) by several gases. A pump-and-probe technique is used; CO(a) is created by pumping the spin-forbidden (a-X) transition at 206 nm. Measured rate coefficients at room temperature are: k(sub Q)(CO) = 5.7 +/- 1.2, k(sub Q)(NO) = 17 +/- 6, k(sub Q)(N2) = 1.4 +/- 0.6, k(sub Q)(O2) = 6 +/- 2, k(sub Q)(H2) = 2.6 +/- 1.0, k(sub Q)(H2O) = 33 +/- 12 in units of 10(exp -11) cu cm/s.
