From 11th international symposium on free radicals; Berchtesgaden, Germany (4 Sep 1973). Absolute rate constants for the reactions of OH radicals with sub 3/CDCD/sub 2/, and CH/sub 2/CH/sub 2/ were determined at 298 deg K. Hydroxyl radicals were generated in the pulsed vacuum-uv photolysis of H/sub 2/O. Decays of OH were monitored by resonance fluorescence in an excess of hydrocarbons. The rate constants for the reactions with propylene and ethylene were determined to be 1.45 ( plus or minus 0.22) x 10/sup -11/ and 3 ( plus or minus 1) x 10/sup -12/ cm /sup 3/ t for deuterated propylene was found to be small, thus supporting the proposed addition mechanism.
