采用可变温度选择的离子流管测量了n= 0-5时CO3−(H2O)n + SO2反应的速率常数。在以下温度范围内，测量了n=0 - 3的温度依赖性：n= 0,158 - 550 K；n= 1,158 - 270 K；n= 2,158 - 193 K；n= 3,158 - 193 K。n= 4,5的速率常数仅在158 K下测量。与先前n=0和1速率常数的测量结果一致。表达式估计用于对流层中SO2的化学电离质谱检测。
The rate constants for the CO3−(H2O)n + SO2 reactions were measured for n=0–5 using a variable temperature‐selected ion flow tube. Temperature dependences were measured for n=0–3 over the following temperature 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 chemical ionization mass spectrometric detection of SO2 in the troposphere.
