气相CH_3OH_2~+离子的碰撞诱导解离谱(CID)的研究

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

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。

Abstract: 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.
