✦ Synopsis

The vibrational fine structure of SO 2 F 2 has been studied in the solid (80 and 15 K), liquid, and gaseous state and in argon matrices (M/S Γ… 30, 100, 300, and 1000) by Raman spectroscopy. Furthermore, the change of the vibrational structure during the phase transition (phase I/phase II) of solid SO 2 F 2 at 65.7 K was observed by temperature-dependent measurements. The Raman frequencies of SO 2 F 2 free of crystal field splitting and molecular rotation were obtained from Raman matrix spectra. The influence of dilution on the matrix-isolated molecules and annealing procedures on the argon matrices with respect to the formation of van der Waals oligomers and matrix effects are discussed.

Experiments are reported which describe the trapping of the unstable fruns conformer of 1.2difluoroethane in argon matrices. Assignments of the infrared spectra of the guuche and rrans conformers are given. The latter is shown to have a 600 c-al/ma1 higher free enthalpy. 1,2difluoroethane (DFE) may

2-fluorovinyl radicals were generated in solid argon by solid-state chemical reactions of mobile F atoms with acetylene and its deuterated analogues. Highly resolved EPR spectra of the stabilized radicals CHF&dbond(\*)CH, CDF&dbond(\*)CD, CHF&dbond(\*)CD, and CDF&dbond(\*)CH were obtained for the fi
