摘要
本文用质量分析离子动能谱/碰撞诱导解离谱和动能释放等方法研究了由甲醇质子转移反应以及CH_3^+和H_2O缔合反应生成的CH_5O^+离子。结果表明上述两种反应生成的CH_5O^+离子结构相同。CH_5O^+离子的碰撞诱导解离谱随离子的内能不同而异。
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.
