Abstract
We describe a series of experiments designed to establish the location of the charge-transfer excited states implied by the double minimum potential energy surface for the gas phase SN2 ion molecule reactions. Two distinguishable species, corresponding to the entrance and exit channel ion dipole complexes, are isolated in an ionized free jet. These complexes are interrogated by photodetachment spectroscopy in addition to the photoexcitation and collisional activation induced fragmentation patterns. Charged transfer excited states are evident in the X- × CH4-nYn (n ≥ 2) species in which dissociative intra-cluster electron transfer yields XY- product ions while the SN2 reaction appears to be driven upon photoexcitation of the 1-•CH3I complex.
