| Abstract: | Photodissociation of (CH3)2N-NO following S1(nπ*) ← S0 excitation yields (CH3)2N? and NO with a quantum yield of 1.03 ± 0.10. These fragments recombine leaving no stable photopioducts. A fraction of NO produced by photolysis is vibrationally excited. The rate of the NO(v = 1) relaxation in collision with (CH3)2N-NO, measured by IR fluorescence, is (1.47 ± 0.03) × 104 s?1 Torr?1. |
