WebMar 16, 2024 · An intriguing aspect of Raman spectroscopy is that information about the vibrational transitions is obtained using visible radiation. The process involves shining monochromatic visible radiation on the sample. The visible radiation interacts with the molecule and creates something that is known as a virtual state. Web2 terms generate absorption (or emission) and Rayleigh scattering, respectively, in the first order terms of a perturbation calculation. However, it is not obvious that a dipole approximation is applicable in describing EM interactions inside HSs, in which EM fields are confined within the order of nanometers as in Figs. 1(b1) and 1(b2).
