用能量分辨串联质谱仪研究了伯醇、仲醇、苯甲醇和苯基取代醇的15个烷基1-甲基吡啶醚衍生物(D+)的裂解。推测了m/z 110、[D-109](+)和[D-111](+)处的裂解途径和机理，包括取代基对主要产物离子形成的影响。比较在相同质心碰撞能(2.0 eV)下得到的异构醇衍生物的产物离子光谱中这些离子的丰度，可以区分一些异构体。版权所有(C)2001 John Wiley Sons，Ltd.
The fragmentation of 15 alkyl 1-methylpyridinium ether derivatives (D+) of primary and secondary alcohols, benzylic alcohols and phenyl-substituted alcohols was investigated using energy-resolved tandem mass spectrometry. Fragmentation pathways and mechanisms, including the influence of substituents, on the formation of the major product ions, which appear at m/z 110, [D - 109](+) and [D - 111](+), were postulated. Comparison of the abundances of these ions in the product ion spectra of isomeric alcohol derivatives, obtained at the same center-of-mass collision energy (2.0 eV), was found to provide the ability to differentiate among some isomers.
