✦ Synopsis

Differences in the ionization enere7 of the uppermost molecules at the crystal surface have been determined forperylene,pyrene, anthracene, chrysene, phenanthrene, and naphthalene from thermally activated electron transfer to oxidized redox ions in aqueous solution. 'These differences are &he same as have been observed for the individual molecules in vacuum. At the boundary to a polarizable medium the ionisation energ is estimated about 0.4 eV smaller than at the organic crystal/vacuum inter-

Triplet escitons at the nnthracene crystal surface yielded a hole photocurrent which was diffusion controlled concerning the excitons at high concentration of the oxidant. Similarities were found in hole photocurrents involving directly excited triplet excitons and in methylene blue sensitized ones.
