Abstract

A pulsed photolysis, laser-induced fluorescence method has been used to study the kinetics of OH (v= 1) and OD (v= 1). The following rate constants (cm3 molecule–1 s–1) for relaxation of these vibrationally excited radicals have been measured at 298±4 K:(a) for OH (v= 1) with HNO3, H2O, NO and NO2:(2.54±0.11)× 10–11,(1.36±0.1)× 10–11,(3.8±0.6)× 10–11 and (4.8±0.8)× 10–11;(b) for OD (v= 1) with DNO3, NO and NO2:(1.53±0.2)× 10–11,(2.7±0.3)× ...
