Coherent Oscillations in the Vibrational Modes of 1-Aminoanthraquinone and Solvent DMSO Manifest the Ultrafast Intramolecular Charge Transfer

Ultrafast charge transfer of 1-aminoanthraquinone with the twist of NH2 group in the excited state is clearly monitored by the coherent oscillations of the coupled vibrational modes of the solute and the surrounding solvent molecules.
