Detection of transient laser magnetic resonance signals in pulsed CO2 laser irradiation of SF6/H2O and SF6/NO mixtures

Abstract A technique for detecting transient far-infrared laser magnetic resonance (LMR) signals, induced by pulsed CO 2 laser photolysis, has been developed. The method is illustrated with preliminary data from photolysis of SF 6 containing H 2 O or NO. In the former mixture. OH(X 2 Π) formation and decay is observed, while in the latter, a transient decrease in NO(X 2 Π) concentration followed by a return to the original value is observed. Possible physical and chemical mechanisms are discussed.
