The rate constants of the gas-phase reaction of OH with SO{sub 2} for M = He, N{sub 2}, and SO{sub 2} have been determined by using the discharge flow/resonance fluorescence technique. The termolecular rate constants (all in units of cm{sup 6} molecule{sup {minus}2} s{sup {minus}1}) and the corresponding experimental conditions are as follows: k(M=He) = (1.1 {plus minus} 0.3) {times} 10{sup {minus}32} exp((640 {plus minus} 200)/T) (280-413 K, 1-6 Torr); k(M=SO{sub 2}) = (3.3 {plus minus} 1.5) {times} 10{sup {minus}31} exp((1,055 {plus minus} 500)/T) (280-363 K, P < 0.23 Torr); k(M-N{sub 2}) = (2.4 {plus minus} 0.7) {times} 10{sup {minus}31} (298 K, 0.6-4.5 Torr).
