Actively phase-locked heterodyne-detected fifth-order nonresonant Raman scattering from room temperature CS2 has been measured. The experimental signals have similar magnitudes, shapes, and sign changes as calculated responses obtained via molecular dynamics simulations [S. Saito and I. Ohmine, Phys. Rev. Lett. 88, 207401 (2002)]. The measured signals contain sign changes that appear to be associated with the coupling of rotational motions both to each other and to translational motions.
已测量了来自室温二硫化碳的主动锁相外差检测的五阶非共振拉曼散射。实验信号与通过分子动力学模拟获得的计算响应具有相似的幅度、形状和符号变化 [斋藤史郎和大峰一，《物理评论快报》88, 207401 (2002)]。测量到的信号包含符号变化，这些变化似乎与旋转运动之间以及旋转运动与平移运动之间的耦合有关。
