Abstract: The reaction processes of ketones in the presence of Nitrogen or Argon by microwave discharge have been studied with the combined technique of ESR and gas chromatography. The results show that free radical reactions initiated by excited N2* (Ar) or N2+* (Ar+*), which were formed in microwave discharge, are the fundamental processes. Reaction mechanisms are discussed.

Key words: Excited state, ESR, Gas chromatography, Microwave discharge
