Research Abstract

The ultimate purpose of this study was real-time observations of hydrogen bond dynamics such as stretchings, dissociations, and rearrangements. I succeeded in tuning intermolecular vibration dynamics of hydrated clusters using so-called messenger-mediated cooling technique. In addition, for real-time observation of molecular dynamics, I designed a femtosecond time-resolved ion/electron imaging setup utilizing my unique concept. I hope these achievements stimulate further studies of molecular dynamics.
