Abstract
General scheme of fragmentation of monofunctional organic compounds RX (R, alkyl and X, functional group) has been elucidated basing on analysis of mass spectra under conditions of electron impact. The mass spectra have been considered as superposition of a few peaks of characteristic ions containing group X or its fragments and the peaks of hydrocarbon ions (hydrocarbon subspectra). The hydrocarbon subspectrum analysis has allowed interpretation of the fragmentation processes forming the RX compounds mass spectra and estimation of contribution of each process into the total ion current. The possibility of simulating the spectra of non-studied compounds RX via the transformation of available mass spectra of RX compounds with the same alkyl fragment is discussed.
