## Abstract The intermolecular interaction energy curves of CH~3~OCH~3~ο£ΏCH~2~F~2~, CF~3~OCH~3~ο£ΏCH~2~F~2~, CF~3~OCF~3~ο£ΏCH~2~F~2~, CH~3~OCH~3~ο£ΏCHF~3~, CF~3~OCH~3~ο£ΏCHF~3~, and CF~3~OCF~3~ο£ΏCHF~3~ complexes were calculated by the MP2 level __ab initio__ molecular orbital method using the 6β311G\*\* basi
A variety of relative and absolute techniques have been used to measure the reactivity of fluorine atoms with a series of halogenated organic compounds and CO. The following rate constants were derived, in units of cm3 molecule-' s-l: CH3F, (3.7 2 0.8) X CH3C1, (3.3 2 0.71 X 10 -'I; CH3Br, (3.0 2 0.
Collisional deactivation of by the title compounds was investigated through 2 I( P ) 1/2 the use of the time-resolved atomic absorption of excited iodine atoms at Rate 206.2 nm. constants for atomic spin-orbit relaxation by CH 3 Cl, CH 2 Cl 2 , CHCl 3 , CCl 3 F, and CCl 4 are and Οͺ13 Οͺ13 Οͺ14 Οͺ15 3.
The reactions of Zn(CF 3 )Br Β΄2 CH 3 CN, Cd(CF 3 ) 2 Β΄2 CH 3 CN or Bi(CF 3 ) 3 /AlCl 3 with tertiary amines lead to the formation of quaternary ammonium salts of the general formula [R 3 NCF 2 H]X. The reaction of 4-N,N-dimethylaminopyridine with Zn(CF 3 )Br Β΄2 CH 3 CN yields (Ndifluoromethyl)-4-N,N
