我们提出了一种相干的强场方法来控制联苯衍生物的扭转模式，并开发了一种数值方案来模拟扭转动力学。通过选择场参数，该方法可以应用于将扭转角驱动到任意配置或引起自由内旋转。建议将瞬态吸收光谱作为扭转控制的探针，并对这种方法的实用性进行了数值探索。考虑了我们操纵分子扭转运动的能力的几个后果。其中包括分子手性反转方法和超快手性开关。
We propose a coherent, strong-field approach to control the torsional modes of biphenyl derivatives, and develop a numerical scheme to simulate the torsional dynamics. By choice of the field parameters, the method can be applied either to drive the torsion angle to an arbitrary configuration or to induce free internal rotation. Transient absorption spectroscopy is suggested as a probe of torsional control and the usefulness of this approach is numerically explored. Several consequences of our ability to manipulate molecular torsional motions are considered. These include a method for the inversion of molecular chirality and an ultrafast chiral switch.
