investigated under electron impact conditions. Collisional activation (CA) and neutralization−reionization (NR) mass spectrometries have allowed the identification of new nitrile N-sulfides (NCCNS, H2NCNS, H3CSCNS, and ClCNS) as ions or neutrals in the gas phase of a mass spectrometer. These results were supported by chemical ionization experiments of nitriles using carbon disulfide as the reagent gas, flash vacuum
1,2,5-噻二唑1 - 5轴承CN,CONH 2,SCH 3,和Cl的取代基已被电子撞击条件下分析。碰撞活化(CA)和中和-再离子化(NR)质谱技术已使新的腈N-硫化物(NCCNS,H 2 NCNS,H 3 CSCNS和ClCNS)可以在质谱仪气相中鉴定为离子或中性离子。这些结果得到了使用二硫化碳作为反应气的腈的化学电离实验,快速真空热解实验以及在G2(MP2,SVP)级别从头算分子轨道计算的支持。中性腈N通过实验和理论发现,硫化物是气相中可观察到的物质。所有的阳离子都是势能极小值,其计算的碎片能与实验观察结果一致。
