On This Day - Nov 07 : Raman was born
He was awarded the Nobel Prize in Physics in 1930 for his work on the scattering of light and the discovery of the Raman effect. This effect is the change in the wavelength of light when a light beam is deflected by molecules. Raman spectroscopy has since become a key tool for chemical characterisation.
