Research Abstract

We investigated the high-energy/multichannel chemical reaction in which the system has much energy as compared with the transition state. The internal energy dependence of the water migration observed in acetanilide-water 1:1 cluster was investigated. Based on the experimental results, it was revealed that the water migration occurring in the higher internal energy region is essentially different from that occurring in the lower internal energy region.
