Vibrational relaxation of SO(X(super 3)summation(super -1), v=1-5) and nascent vibrational distributions of SO generated in the photolysis of SO2 at 193.3 nm

Rate coefficient for deactivation of SO(X(super 3)summation(super -), v=1-5) by collisions with SO2 and nascent vibrational populations in v= 0-2 in the photolysis of SO2 is presented. The findings indicate that the vibrational level dependence of the deactivation rate coefficients is small and 63% of the relaxations of v=2 by SO2 proceed is double-quantum relaxation.
