Large Molecular Third-Order Optical Nonlinearities in Polarized Carotenoids
Carotenoids Molecular Structure Optics and Photonics Photochemistry Spectrum Analysis
2016/5/23
Garito and co-workers have suggested a mechanism to dramatically increase the second hyperpolarizability, gamma, in linear pi-electron-conjugated molecules. Polarization is introduced that leads to a ...
Polarization Selectivity of Third-Order and Fifth-Order Raman Spectroscopies in Liquids and Solids
Polarization Selectivity Third-Order and Fifth-Order Raman Spectroscopies Liquids and Solids
2014/9/24
Polarization selectivity of third-order and fifth-order Raman spectroscopies is examined for both isotropic liquids and periodic lattices. Our approach directly applies the symmetry property of the pr...
