Влияние Степени Окисления Атома Серы На Пути Фрагментации S-содержащих Производных 1,2,4-Триазола При Ионизации Электронами

Measurements of mass-spectromical characteristics of molecular ions and precise values of mass numbers of all significant ion peaks in electron ionization mass-spectra of 3-brom-(4-nitroethyliden)-hydrazino-(1-tiethanil-3)-1,2,4-triazol (1) and its 1-oxo(2) and 1,1-dioxo(3) derivatives are carried out. Properties of the highest occupied molecular orbitals are shown to influence significantly on the analyzed compounds mass-spectra generation processes. The increase of sulphur atom oxidation degree leads to ione electron pair disappearance and sulphur containing fragments contribution reduction.
