Visualizations of electric and magnetic interactions in ECD and ROA
Abstract
The chiral source and its mechanism in the molecular system are of great significance in many fields. In this work, we proposed visualized methods to investigate physical mechanism of chiral molecule, where the electric and magnetic interactions are visualized with the transitional electric dipole moment, the transitional magnetic dipole moment and the transitional electric quadrupole moment, and their tensor product. The relationship between molecular ROA response and molecular structure was analyzed in an intuitive way. The relationship between chromophore chirality and molecular vibration mode are revealed via interaction between the transition electric dipole moment and the transition magnetic dipole moment. The molecular chirality is derived from the anisotropy of the molecular transition electric dipole moment and the transition magnetic dipole moment. The anisotropic dipole moment localized molecular chromophore is the source of the vibration mode in which the ROA responds to the reverse.
