PPT PowerPoint Presentation Raman shifted photons can be of either higher or lower energy, depending upon the vibrational state of the molecule under study. Kaipparettu, A.A. Marti, T. Hayashi, J.-J. It results in emission process Therefore, to obtain Raman spectra, it is necessary to prevent Rayleigh scattering from overpowering the weaker Raman scattering.
