英文摘要：

The formation of secondary organic aerosol products from the gas-phase ozonolysis of 1-methylcyclohexene was investigated in static chamber experiments.A range of multifunctional organic acids were identified in the condensed phase using gas chromatography coupled to mass spectrometry after derivatization.Products yields were found to be a function of different ·OH radical scavengers and relative humidity,which provided to give information about the reaction mechanisms.On the basis of experimental findings,previously proposed mechanisms were evaluated and detailed gas-phase mechanisms were developed to explain the observed product formation.
