论文摘要
手性的四波混合信号是使用不可约张量形式主义计算的。不同的极化和交叉角度构型可以挑出磁偶极子和电二极管相互作用。其他配置可以揭示手性相互作用发生在给信号的非线性相互作用途径内的给定步骤中。通过手性刺激的X射线拉曼信号在碳K边缘和手性可见的2D电子光谱刺激的X射线拉曼信号中，对S-无胶体的价激发进行了应用。
Chiral four-wave-mixing signals are calculated using the irreducible tensor formalism. Different polarization and crossing angle configurations allow to single out the magnetic dipole and the electric quadrupole interactions. Other configurations can reveal that the chiral interaction occurs at a given step within the nonlinear interaction pathways contributing to the signal. Applications are made to the study of valence excitations of S-ibuprofen by chiral Stimulated X-ray Raman signals at the Carbon K-edge and by chiral visible 2D Electronic Spectroscopy.teraction pathways contributing to the signal.
