摘　　要：本文报道了一些取代的三唑，四唑及噻二唑类化合物的电子轰击质谱。它们的裂解途径表明，对于合侧链的化合物，存在有McLafferty重排以及涉及C－2和C－3键断裂的裂解过程。The electron impact mass spectra of some triaaole,thiadiazole and tetrazole derivatives are reported. The McLafferty rearrangement involving the γ-hydrogen transferfrom the alkyl chain dominates the mass spectra of many of the compounds. The preferable cleavage of C-C bond hetween C-2 and C-3 of the alkyl chain is also observed.
