Abstract
Coherent nuclear wave packets in the product state launched by the ultrafast intramolecular charge transfer are observed by time-resolved fluorescence with 40 fs time resolution. Direct information on reaction coordinates and structural changes can be obtained.
Highlights
Intramolecular charge transfer (ICT) is one of the most important reactions for its usefulness in applications such as the bio-imaging as well as the fundamental importance
The ICT reaction may proceed through the twisting of the dimethylamino group, its dynamics including the structural change still remains under intense investigation because of the conflicting experimental and theoretical reports [3,4]
We have studied the ultrafast ICT dynamics by time-resolved fluorescence (TRF), which gives the signal from the excited state exclusively
