What is Raman Shift?
The
Raman shift refers to the change in wavelength of light that occurs when a light beam is scattered by molecules. When light interacts with molecular vibrations, phonons, or other excitations in the material, it can gain or lose energy. This energy shift is detected and analyzed in
Raman Spectroscopy, providing valuable information about the molecular composition and structure of the material.
