Abstract
The kinetics of the quenching of metastable O(1S) atoms by a number of chlorofluoromethanes has been studied by a pulsed VUV resonance lamp for the generation of the metastable species and by the forbidden tran sition at 557 nm for their detection. The rate constants of all invest igated quenchers are temperature independent in the range from 215 to 445 K. The constants vary greatly from 15 x 10(-10) to 2.2 x 10(-17) c m3 s-1 and depend considerably on the number of Cl atoms of the methan es.
