摘要：

Methyl hydroperoxide (CH3OOH) is one of the main organic peroxides in the atmosphere, and its formation and removal processes will have a significant impact on the concentration level of the atmospheric radicals. In the present paper, the technique of long path Fourier transform infrared (LP-FTIR) spectrometry was used for the in-situ investigation of the UV-photolysis of CH3OOH under atmospheric conditions at normal temperature and pressure. The products of photolysis were identified as HCHO, HC(O)OH, CH3OH, CO and CO2. Moreover, OH radicals were also detected. Finally, the mechanisms of this reaction were extrapolated on the basis of the analysis results, and the atmospheric implications were discussed.
