USING the 2536.5 radiation of the mercury arc as the exciter and a Hilger Intermediate quartz spectrograph, the faint second-order Raman spectrum of diamond was first successfully recorded by me 1.

Definition:Raman Spectroscopy is a sophisticated analytical technique used to observe vibrational, rotational, and other low-frequency modes in a system. This material characterization technique ...

In Raman spectroscopy, a laser is used to irradiate ... known as Raman scattering. This process was first observed by Indian scientist Sir Chandrashekhara Venkata Raman in 1928.
