N2  - Hydrogen atom abstraction from (CH3)2S by CF3 radicals has been studied in the temperature range 79-167º:     (1)  CF3 + CH3SCH3 &#8592;&#8594; CF3H + CH3SCH2  (-1)  The rate constant, based on Ayscough's value of 1013.36cmS mol-l s-l for the recombination of CF3 radicals, is given by (k1 in cm3 mol-1 s-l, E in J mol-l):   Logk1 = (12.05 ± 0.02)-(28710 ± 130)/2.303RT Combination of these results with thermochemical data gives a calculated value of     log k-1 = 12.2 - 62600/2.303RT   for the rate constant of the reverse reaction.   &#916;Hºf(CH3SCH2) and Sº(CH3SCH2) are estimated to be 155.6 kJ mol-l and 290 J K-l mol-1 respectively.
