The 193 nm photodissociation of the isotopomers SOz, SO: and SOO' (with O\*= '\*O) was studied by high-resolution photofragment translational spectroscopy. The translational energy distributions P(&) of the fragment pairs SOtO, SO'tff, SOt(T and SO\*+0 were determined from systematic analysis of the

โฆ Synopsis
A molecular beam of SO* has been photodissociated at I93 nm to measure both the translational energy and angular distributions, from which it is concluded that the photodissociation is predissociative and that the vibrational population is peaked at un =2.

A molecular beam of C,F,CI was photolyzed using an excimer iaser at 193 nm. Measurements of time-of-flight dtstributions of the Cl photofragment revealed a prominent fluorination effect on the dissociation process, namely a large reduction of the kinetic energy of the fragments. The dominant process
Molecular hydrogen is observed to be one of the major primary products in the 193 nm photodissociation of phenylstlane. A two-channel dissociation mechanism is proposed, yielding PhSiH + H, and SiH, + PhH with the former predominant. The implications of this observation for experiments which utilise
We have generated a cold beam of the highly corrosive sulfur trioxide SO3 and have studied its photodissociation at 193 nm by photofragment translational spectroscopy, The spin-allowed process SO3( g 'A{) + hv --+ SOs( ji 'Al ) + 0( 'D) was found to be the primary dissociation channel. A part of the
