Observation and control of conformation dynamics by intense coherent light

频率域和实时域的相干非线性光谱被用于观察和控制能够灵活改变其结构的分子体系的构象动力学。详细研究了几种含苯分子团簇的大幅度取向变化，并通过强非共振超快脉冲辐照实现了分子间振动的相干激发。目前的实验成果有望导致对柔性分子异构化的相干控制。

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.
