Abstract:Electron-impact-induced phosphorescence of biacetyl was observed at low vapor pressures. Excitation functions and decay characteristics of the phosphorescence were measured as functions of pressure. Mechanisms of triplet formation under electron impact are discussed in terms of these results as well as previously reported electron spectroscopic data.
