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
Emission processes from lower excited states S1 (fluorescence) and 2' 1 (phosphorescence) have been studied in the gas and liquid phases when biacetyl is excited into the second singlet state Sz. (In agreement with Kasha's rule no fluorescence is observed from the S2 state.) In the liquid phase, wh
Emission spectra have been recorded and decay times measured for biacetyl seiectively ewited in the 0: band of the Sr-So ('A,-'Ag) transition\_ The spectrum of the "long emission" corresponds to a superposition of the fluorescence and of the "hot" phosphorescence\_ The results may be treated in term
