Twisted intramolecular charge transfer and the torsional potential function of dimethylaminobenzonitrile

摘要

Recent experimental and theoretical studies of the twisted intramolecular charge transfer process and its interdependence with the torsional potential for dimethylaminobenzonitrile (DMABN) are discussed. It is shown that while the available experimental and theoretical evidence does not effectively discriminate between an untwisted or twisted ground state for DMABN in either the gas phase or solution, strong indirect evidence exists for a twisted DMABN ground state in the presence of a polar solvent.
