Abstract

Photoelectron imaging results are presented for I -X cluster anions (X CO 2, C 4H 5N pyrrole, (CH 3) 2CO, CH 3NO 2). The available detachment channels are labeled according to the neutral iodine atom states produced (channel I 2P 32 and channel II 2P 1/2). At photon energies in the vicinity of the channel II threshold these data are compared to previously reported results for I -X (X CH 3CN, CH 3Cl, CH 3Br, and H 2O). In particular, these results show a strong connection between the dipole moment of the solvent molecule and the behavior of the channel I photoelectron angular distributions in this region, which is consistent with an electronic autodetachment process. The evolution of the channel II:channel I branching ratios in this excitation regime supports this contention.
