Coaxial Measurement of the Translational Distribution of CS Produced in the Laser Photolysis of CS2 at 193nm.

Abstract

The coaxial translational time of flight (TOF) distributions of CS radicals produced in the 193nm laser photolysis of carbon disulfide have been measured. The population of CS with low translational energy is higher in the coaxial TOF measurements than it is with perpendicular measurements. These distributions have been analyzed using the Kresin-Lester adiabatic theory of photodissociation to obtain an upper limit for the S(3P)/S(1D) branching ratio of 2.1. If this analysis is correct it also suggests that significant amounts of CS radicals are produced in vibrational levels as high as v = 12 and that there are angular momentum constraints in the photodissociation process.
