Abstract
The mass spectra of methyl-substituted biquinolinyls have been studied and the stabilities of their molecules to electron impact have been determined. It is assumed that the decomposition of the systems studied under the action of electron impact takes place predominantly from the excited molecule, which exists in the form of the trans or the cis isomer, and proceeds through a stage of the formation of rearrangement ions consisting of multiring condensed systems. A difference has been observed in the probability of the formation of doubly charged ions. A scheme of identification is given.
