| Research Abstract |
Transient rotations of・-electron in a chiral aromatic molecule are induced by applying linearly polarized femtosecond UV laser pulses, and coherent ring currents are created. Its direction depends on the molecular chirality. Different behaviors in nuclear wavepackets between S-and R-enantiomers were found by taking into account nonadiabatic couplings between electronic and vibrational motions. These findings give the fundamental principles of new ultrafast method for identification of molecular chirality.
