摘要：

The reaction of peroxy radicals, RO2, with OH radicals has long been ignored to play any role in atmospheric chemistry. Recent experimental and modeling studies show however that these reactions are fast and can play a role in remote atmospheres with low NO concentrations when the major fate of peroxy radicals, its reaction with NO, slows down. The present article summarizes recent work on this class of reactions and its implications in different environments.
