Intense single-cycle THz pulses resonantly interacting with molecular rotations are shown to induce field-free orientation and alignment under ambient conditions. We calculate and measure the degree of both orientation and alignment induced by the THz field in an OCS gas sample, and correlate between the two observables. The data presents the first observation of THz-induced molecular alignment in the gas phase.
强单周期太赫兹脉冲与分子旋转共振相互作用，在环境条件下诱导无场取向和排列。我们计算和测量了太赫兹场在ocs 气体样品中诱导的取向和排列程度，并对这两个可观测量进行了相关分析。该数据首次观察到了太赫兹诱导的气相分子排列。
