摘要: We propose a coherent, strong-field approach to control the torsional modes of biphenyl derivatives, and develop numerical scheme simulate dynamics. By choice field parameters, method can be applied either drive torsion angle an arbitrary configuration or induce free internal rotation. Transient absorption spectroscopy is suggested as probe usefulness this numerically explored. Several consequences our ability manipulate molecular motions are considered. These include for inversion chirality ultrafast chiral switch.
