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

β¦ Synopsis
The photodissociation of iodine monochloride following excitation at 235 nm, within its second absorption band, has been investigated further using ion imaging methods to monitor the Cl(2P~/2 ) and C1 * (2P~/2) atomic products. The angular distributions of these products are found to be characterised by anisotropy parameters, /3 = 1.8 _+ 0.2 and -1.0 _ 0.1 for the Cl and CI * products, respectively, whilst the measured Cl/C1 * translational energies indicate the involvement of the two product channels: IC1 + h~,(A = 235 nm) ~ Cl + I * (2P~/2) and Cl* + I(2P3Β°/2).

## Abstract In a crossed laserβmolecular beam study of nitromethane it was found that the excitation of nitromethane at 266 nm did not yield dissociation products under collisionβfree conditions. When a small cluster of nitromethane was excited at the same frequency, the product was seen only at en
Using the laser photolysis/laser-induced fluorescence (LP/LIF) pump-probe technique, the gas-phase photodissociation dynamics of room temperature HNCO was studied at a photolysis wavelength of 248 nm. H atoms produced via HNCO + hv ~ H(2S)+ NCO(X 2H) were detected by vacuum-UV laser-induced fluoresc
