A Study on Collisional Induced Dissociation Spectra of CH_3OH_2~+ in Gas Phase

CH_5O~+ ions produced by proton-transfer reaction on CH_3OH as well as association reaction between CH_3~+ and H_2O are studied by means of MIKES/CID and kinetic energy release. The resuits show that two reactions produce the same structure ions of CH_5O~+. The kinetic energy release is a probe of ion structure. The CID spectra are dependent on the internal energy of ions.
