Abstract
The rate constants for the CO3-(H2O)(n) + SO; reactions were measured for n = 0-5 using a variable temperature-selected ion flow tube. Tempe rature dependences were measured for n = 0-3 over the following temper ature ranges: n = 0, 158-550 K; n = 1, 158-270 K; n = 2, 158-193 K; n = 3, 158-193 K. The n = 4, 5 rate constants were measured exclusively at 158 K. Good agreement is found with previous measurements of the n = 0 and 1 rate constants. Expressions are estimated for use in chemica l ionization mass spectrometric detection of SO2 in the troposphere.
