The gas-phase clustering reactions of SF~, SF 6 and F-ions with SF 6 were measured using a high-pressure mass spectrometer. The bond energies of SFs--(SF6) 1 and SF6(SF6) 1 were estimated to be ~< 2.3 kcal/mol. The bond energies of F-(SF6) , with n = 1 and 2 were determined to be 5.4 and = 4.1 kcal/

β¦ Synopsis
The gas phase chemical kinetics of SF,, SF5, and SLF,, are reviewed with particular emphasis on relevance to the general problem of the dielectric breakdown of SFs. Specific reaction systems treated are SF, + F,, SF, + SF,, and the pyrolysis of S2Flo. Computer modeling calculations were carried out to arrive at the best estimates of rate parameters. Based on the results of these calculations, sets of recommended rate parameters are provided, The major discrepancies and problems in establishing the kinetic data base are described. Thermochemical consequences of different model calculations are given.

High level ab initio MO calculations at the G3(MP2) level of theory were employed to study the molecular structures of SF 2 , FSSF 3 , and SSF 4 , as well as the dimerization of gaseous SF 2 to FSSF 3 and the isomerization of FSSF 3 to SSF 4 . The dimerization of SF 2 was calculated to be an exother
## Abstract The kinetics of the gasβphase elimination of benzaldoxime was determined in a static reaction system over the temperature and pressure range 350Β°Cβ400Β°C and 56β140 Torr, respectively. The products obtained were benzonitrile and water. The reaction was found to be homogeneous, unimolecul
The gas-phase elimination kinetics of primary, secondary and tertiary b-hydroxynitriles were examined in static seasoned vessels over the temperature range 360-450 Β°C and pressure range 47-167 Torr (1 Torr = 133.3 Pa). These reactions are homogeneous, unimolecular and follow a first-order rate law.
