Hyper-Raman Scattering: A Powerful Tool To Probe The Structure In Glasses

Hyper-Raman scattering (HRS) is a non-linear optic process in which two incident photons of frequency omega (i) scatter a photon of frequency omega (s) after interaction with a vibrational excitation sigma of frequency omega ( sigma ) = omega (s) - 2 omega (i) in the media. The main interest of HRS...

Description
Summary:Hyper-Raman scattering (HRS) is a non-linear optic process in which two incident photons of frequency omega (i) scatter a photon of frequency omega (s) after interaction with a vibrational excitation sigma of frequency omega ( sigma ) = omega (s) - 2 omega (i) in the media. The main interest of HRS is that the selection rules are different from those of Raman and Infrared absorption. The Hyper-Raman spectroscopy of various silicate and borate glasses has been performed. The selection rule analysis is based on a simple structural model considering a randomly connected network of well defined elementary structural units (ESUs).
