Raman effect

Raman effect
Raman effect n a change in frequency undergone by a portion of the light that has been scattered in passage through a transparent liquid, solid, or gas whose characteristics determine the amount of change

* * *

when a substance is irradiated with monochromatic light, the spectrum which the substance scatters contains, in addition to a line of the same wavelength as the incident radiation, lines which are satellites of the primary line moving with it when the wavelength of the primary radiation is altered.
