Landmark designation
The American Chemical Society and the Indian Association for the Cultivation of Science designated the discovery of the Raman Effect as an International Historic Chemical Landmark in a ceremony on December 15, 1998 at the Indian Association for the Cultivation of Science in Calcutta, India. The plaque commemorating the event reads:
At this institute, Sir C. V. Raman discovered in 1928 that when a beam of coloured light entered a liquid, a fraction of the light scattered by that liquid was of a different colour. Raman showed that the nature of this scattered light was dependent on the type of sample present. Other scientists quickly understood the significance of this phenomenon as an analytical and research tool and called it the Raman Effect. This method became even more valuable with the advent of modern computers and lasers. Its current uses range from the non-destructive identification of minerals to the early detection of life-threatening diseases. For his discovery Raman was awarded the Nobel Prize in physics in 1930.
