Abstract: | A number of symmetrical and unsymmetrical azo compounds have been studied by electron impact mass spectrometry. In all cases (except azoisobutyronitrile) the compounds follow a two-step fragmentation mechanism documentclass{article}pagestyle{empty}begin{document}$ left[{{rm R}^{rm 1} - {rm N = N - R}^{rm 2} } right]_{}^{_.^ + } $end{document} → [R1?
