Photoelectron imaging probes both molecular electronic structure and electron molecule interactions. In the current work images were recorded for detachment from the I-center dot C4H5N(1(-)center dot pyrrole) Cluster anion at wavelengths between 360 and 260 nm. The direct detachment spectra show strong similarities to those of I-, although a strong solvent shift, broadening and some Structure is observed, A nondirect, dissociative or autodetachment feature is also observed over it range of wavelengths. Ab initio calculations identify several local minima associated with neutral and anion isomers. Energy and Franck-Condon arguments are used to assess the role of these in the detachment process. The cluster anion structure is essentially an I atomic anion in the presence of a neutral pyrrole molecule. The spectral structure arises due to interactions in the open shell neutral cluster residue resulting from detachment. The indirect detachment feature arises through the formation of an intermediate dipole hound Cluster anion State Which Subsequently dissociates. The energy dependence of this channel (observed over a 0.6 eV range of photon energies) is discussed in terms of the wide amplitude motions associated with the van der Waals modes of the cluster anions.
