ISOTOPE EFFECTS AND WAVELENGTH DEPENDENCE IN THE ROTATIONAL STATE DISTRIBUTIONS OF THE DIATOMIC PHOTOFRAGMENTS SH AND SD FROM THE PHOTODISSOCIATION OF H2S AND D2S

We employ a semi-empirical model that utilizes a kinematic distributio n function to calculate the rotational state population distributions of diatomic photofragments from the photodissociation of isotopically variant triatomic molecules. The numerically evaluated rotational dist ributions of the photofragments, SH and SD, are compared with experime ntal data on the nascent rotational state population distributions of the diatomic photofragments resulting from the laser photolysis of H2S (lambda(photolysis)=193, 222 and 248 nm) and D2S (lambda(photolysis)= 193 and 222 nm).
