Abstract:
Intramolecular charge transfer in aminobenzonitrile (DIABN) single crystals is studied by a combination of ultrafast techniques. The intramolecular dynamics are probed by time-resolved spectroscopy in the UV/vis and mid-IR. The intermolecular structural response is investigated by transient X-ray scattering and transmission experiments. A theoretical analysis shows that diffuse scattering and dipole solvation determine the X-ray data. The observed dynamics result from charge transfer reaction leading to strong local changes of molecular dipole moments and related structural rearrangements in the crystal.
