India celebrates National Science Day on 28 February of every year to commemorate the discovery of the Raman effect in 1928. [196] Postal stamps featuring Raman were issued in 1971 and 2009. [197] A road in India's capital, New Delhi, is named C. V. Raman Marg. [198] An area in eastern Bangalore is called CV Raman Nagar. [199]
The inverse Raman effect is a form of Raman scattering first noted by W. J. Jones and Boris P. Stoicheff. In some circumstances, Stokes scattering can exceed anti-Stokes scattering; in these cases the continuum (on leaving the material) is observed to have an absorption line (a dip in intensity) at ν L +ν M.
Raman signal enhancements are achieved through non-linear optical effects, typically realized by mixing two or more wavelengths emitted by spatially and temporally synchronized pulsed lasers. Hyper Raman – A non-linear effect in which the vibrational modes interact with the second harmonic of the excitation beam. This requires very high power ...
[8] His Royal Society candidature certificate in 1935 read: "Distinguished for his investigations in molecular optics and in magne-crystalline action:collaborated with Sir C.V. Raman in extensive theoretical and experimental studies on light scattering, molecular optics and in the discovery of the Raman Effect (1928). More recently has been ...
National Science Day is celebrated in India on February 28 each year to mark the discovery of the Raman effect by Indian physicist Sir C. V. Raman on 28 February 1928. For his discovery, Sir C.V. Raman was awarded the Nobel Prize in Physics in 1930.
CV Raman was born in Trichy, Tamil Nadu to Tamil parents, Chandrashekaran Ramanathan Iyer and Parvathi Ammal. At an early age, Raman moved to the city of Visakhapatnam and studied at St Aloysius Anglo-Indian High School. [2]
They found the same combinational scattering of light. Raman stated that "The line spectrum of the new radiation was first seen on 28 February 1928." [6] Thus, combinational scattering of light was discovered by Mandelstam and Landsberg a week earlier than by Raman and Krishnan. However, the phenomenon became known as the Raman effect because ...
Adolf Gustav Stephan Smekal (12 September 1895 – 7 March 1959) was an Austrian theoretical physicist, with interests in solid state physics, [1] known for the prediction of the inelastic scattering of photons (the Raman effect).
