An experimental <physicist> who, with <Chandrasekhara Venkata Raman>, reported frequency-shifted light scattered by liquids. Their photographs compare filtered mercury-lamp light with the scattered spectrum, showing additional lines absent from the input. The <Raman effect> turns exchange of energy with molecular motion into spectral shifts, making scattered light a probe of molecular structure.<The Optical Analogue of the Compton Effect by Chandrasekhara Venkata Raman and Kariamanikkam Srinivasa Krishnan>[Abstract and Figure 1: filtered incident spectrum and additional scattered lines]{ref}
