Research Abstract

Coherent nonlinear spectroscopy both in frequency and real-time domains has been implemented for observation and control of conformational dynamics of molecular systems that can flexibly transform their structures. Large-amplitude orientational changes in several molecular clusters containing benzene have been identified in details, and coherent excitation of intermolecular vibrations has been realized by the irradiation of intense nonresonant ultrafast pulses. The present experimental attainments are expected to lead to coherent control of isomerization of flexible molecules.
