Phenanthrene is studied by photodetachment-photoelectron spectroscopy. Due to the absence of a parent ion peak in the anion mass spectrum the electron affinity could not be detd. directly. However, this absence is the first indication that this mol. has a neg. electron affinity. The first three water complexes of phenanthrene were studied, supplying insights into its microsolvation property. Moreover, the electron affinity of the bare mol. could be detd. to be -0.01±0.04 eV by an extrapolation method using the water cluster data. The exptl. work is supported by ab initio calcns. for detg. the structure of the water complexes. Finally a correlation between the electron affinity and the redn. potential of polycyclic arom. hydrocarbons is investigated. [on SciFinder(R)]
