The determination of electron transfer equilibria A-+ B = A + B-in the gas phase, with a pulsed-electron highpressure mass spectrometer, leads to AGIO, AH,', and ASlo values. These can be converted into the free energy, enthalpy and entropy changes, AGC(B), AH,O(B) and AS,O(B), for the reaction e +

Cross sections for photoionization of molecular anthracenc and for photogeneration in the solid are calculated using approximate wavefunctions and assuming the process to occur by a transition directly into a simple continuum. 'lhe results differ from earlier reported values, are in better agrccmcnt
Two mechanisms are responsible for the flash induced ionization of peryiene in aeetonitrile: a bimotecular reaction between an excited and an unexcited perylene molecule. and, at shorter exciting wzvelengths, direct dissociation of some higher excited singlet state.
The delayed fluorescence (DF), the action DF spectrum, the incident light intensity dependence of the DF and the DF decay of an anthraoene single crystal at 77ยฐK arc analyzed. It is proposed that the delayed fluorescence originates from electron-hole recombinations after photogeneration of charge ca
