The Application of the Molecular Orbital Theory to the Bond Scissiom of Aliphatic Amines

The relative scission-probabilities of C–C bonds of n-propyl, n-butyl and isobutyl amines being formed by electron impact (90 V.) were determined by the use of mass spectrometers of the usual type and of the high-resolution type. They were in good accordance with the theoretical values calculated by the LCBO-MO theory which had been proposed and found successful in explaining the mass spectra of n-paraffins and methyl alkyl ketones.
