摘要 本文报道了在280-286．5nm区域内，通过共振增强多光子电离-时间飞行质谱和质量选择光电离激发谱对二甲基硫分子的光电离和光解离通道进行了研究．实验结果表明．在280～286．5mn区域内．二甲基硫分子以母体分子的电离通道为主．即首先电离生成母体离子然后母体离子再解离生成碎片离子． Resonance Enhanced Multiphoton Ionization （REMPI） dissociation channels of dimethyl sulfide were studied using REMPI-TOF-MS and mass - selected excitation spectra in the range of 280- 286.5 nm. It was shown that the main dissociation channel of dimethyl sulfide is the photoionization of parent molecule firstly in the range of 280-286.5 nm, then followed by photodissociation of parent ion.
