The electronic structure, geometry, vibrational frequencies and intensities for the gound and !irst excited states of the trifhrorometho\y radical have been calculated at the RIiF/3-21C level of theory. The consequences of Jahn-Teller distortion and of negative hyperconjugation are discussed and the

โฆ Synopsis
Trifluoromethoxy radical formation (by O-atom addition to trifluoromethyl) and dissociation (by F-atom elimination) are studied by ab initio molecular-orbital theory. The activation enthalpy (298 K) for F-atom elimination is 35.3 kcal mol-' at the UMP4SDQ/6-3 1 G*NUHF/6-3 1 G* + AZPE +A( H-E,) level. The implication of calculated RRKM dissociation rate constants is discussed.

The translational energy spectrum of H Rydberg atoms resulting from the photolysis of methanethiol ( CHsSH ) at 2 16 nm includes peaks which arise from the secondary photolysis of methyl radicals -one of the primary products. The measured times of flight of these secondary H atoms indicate that the
The ionization and lowest energy unimolecular dissociation of tert-butanol were modelled by ab initio molecular orbital methods. The ion is formed on a repulsive surface and gives a methyl radical and protonated acetone as products with the liberation of 0.54 eV of energy. The calculations predict t
