When light is scattered from an atom or molecule ,most photons are elestically scattered.such scattering that was the scatterd photons have the same energy[frequency] and wavelenght as the incident photons .However a small fraction of the scattered light[approximately 1 in 10 million photons] is scattered by an excitation with the scattered photons having a frequesncy different from and ususlly lower than,the frequecny of the incident photons,which phenonmenon i am talking about?

Hi codeofuniverse .
Despite the fact I need a cup of coffee or a tad of tea to perk me up, I'll take a stab at this one. Would that phenomena be called atrophy?
I was thinking at first the frequency would be higher, but then, no logically it would be lower due to atrophy.
