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.
Am&-The reduction of pyrene (Py) at a mercury channel electrode is studied in acetonitrile solution, both in the dark and under conditions where the pyrene radical anion (Py-.) is photoexcited, using a wavelength of 501.7 nm. In the dark a reversible one-electron process occurs forming the radical a
