The S-34 and C-13 isotopic fractionations in the OCS + OH reaction are investigated using RRKM-theory. The reaction proceeds via different channels, at low pressures a channel leading to CO + SOH dominates. While with increasing pressure an adduct...

The sulfur kinetic isotope effect (KIE) in the reaction of carbonyl sulfide (OCS) with O(P-3) was studied in relative rate experiments at 298 +/- 2 K and 955 +/- 10 mbar. The reaction was carried out in a photochemical reactor using long path FTIR...
