The authors have used femtosecond photoelectron spectroscopy to monitor the dynamics associated with the charge-transfer-to-solvent (CTTS) states in I{sup {minus}}(Xe){sub n} clusters. The authors find that the lifetime for the {sup 2}P{sub 1/2} CTTS state increases approximately linearly with cluster size, e.g. 550 {+-} 50, 700 {+-} 50, and 1,550 {+-} 200 fs for clusters n = 11, 20, and 38, respectively. These states are determined to decay by spin-orbit autodetachment. In contrast, the {sup 2}P{sub 3/2} CTTS state has a lifetime greater than 225 ps for even the smallest cluster studied, n = 6. No evidence for solvent reorganization is observed in the photoelectron spectra.
