Emission in the ultraviolet–visible region produced by the electron-impact excitation of polyatomic molecules. Part 1. Amino-compounds
Abstract
The electron-impact induced optical emissions of a series of amino-compounds have been studied using single electron–molecule collision conditions. Various excited fragment radicals have been observed from all the amines, together with an excited molecular emission from non-aromatic tertiary amines. No electronically excited ionic states were observed. The formation of electronically excited neutral molecules is shown to occur by both electric-dipole allowed and electric-dipole forbidden excitation processes.
