Ra·man ef·fect

a change in frequency undergone by monochromatic light scattered in passage through a transparent substance the characteristics of which determine the amount of change, yielding a spectrum in which the incident wavelength band is flanked by small satellite bands of greater and lesser wavelengths.

Raman effect

The effect that occurs when a beam of incident light causes rotational and vibrational transitions in molecules, resulting in scattered light which exits at a different frequency than incoming light.


Sir Chandrasekhara Venkata, Indian physicist and Nobel laureate, 1888-1970.
