本文应用腔衰荡光谱法研究了NO3与CH3I在20 ~ 200torr的N2稀释剂中在298 K下的反应动力学。测定了NO3 + CH3I反应的速率常数为（4.1 +/- 0.2）× 10(-13) cm3分子（-1）s(-1)，在100torr的N2稀释剂中，在298 K下，与压力无关。这一反应可能极大地促进了大气中活性碘化合物的形成。
We have applied cavity ring-down spectroscopy to a kinetic study of the reaction of NO3 with CH3I in 20-200 Torr of N2 diluent at 298 K. The rate constant of the reaction of NO3 + CH3I was determined to be (4.1 +/- 0.2) x 10(-13) cm3 molecule(-1) s(-1) in 100 Torr of N2 diluent at 298 K and is pressure-independent. This reaction may significantly contribute to the formation of reactive iodine compounds in the atmosphere.
