本文报道了1-（2-噻吩基）己烷-1-13 C的质谱。描述了母离子的主要碎裂途径。烷基链的β裂解占主导地位，标记保留表明α碳原子保留在带电环部分。m/e 97离子的大部分经历环膨胀成六元环。发生少量的烷基链α裂解，预期会丢失标记物。来自初始α或β裂解的离子的进一步碎裂产生类似的碎片离子。值得注意的是，在碎片离子形成过程中损失的许多中性粒子是烷基苯或其他芳族离子体系中遇到的典型粒子。
The mass spectrum of 1-(2-thienyl) hexane-1-13C is reported. The principal fragmentation routes ofthe parent ion are delineated. Beta cleavage of the alkyl chain predominates, and the label retention indicates that the alpha carbon atom remains with the charged ring moiety. A substantial part of the m/e 97 ion undergoes a ring expansion to a six membered ring. A small amount of alpha cleavage of the alkyl chain occurs with the expected loss of the label. Further fragmentation of the ions from initial alpha or beta cleavage produces similar fragment ions. It is noted that many of the neutral particles lost in the formation of the fragment ions are typical of those encountered in the alkylbenzenes or other aromatic ion systems.
