โฆ Synopsis
Rate constants for the reaction of OH radicals with CCS and CS, have been determined at 296 K using the flash photolysis resonance fh~orescen~ technique. The values derived from this study are kOH +mS = (5.66 * 1.21) X lo-l4 cm3 mokcuk-' s-l a& _+OH + CS2 = (1 .I35 2 0.34) X lOmu cm3 molecu!e-' s-l, where the uncertaintks are 95% confidence limits making allowance for possible systematic errors.
