Abstract: The structures of CH_5O~+ from two different reactions which are protonation of CH_3OH and association of CH_3~+ with water were studied by means of CID experiment and MNDO semiempirical calculation The results showed that the CH_5O~+ ions produced from the above two pathways possess the same structure,CH_3OH_2~+.The value of kinetic energy release for the metastable decomposition CH_3OH_2~+→CH_2OH~++H_2 determined from the experiment is in good agreement with that from theoretical calculations. The transition state of above reaction were disscussed.

Key words: CH5O+, CID, MNDO
