The Studies of Electron Impact Mass Spectra of Some Heterocyclic Compounds

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.
