The Raman effect is named after Indian scientist C. V. Raman, who discovered it in 1928 with assistance from his student K. S. Krishnan. Raman was awarded the 1930 Nobel Prize in Physics for his discovery of Raman scattering. The effect had been predicted theoretically by Adolf Smekal in 1923.
[88] [89] Use of the English versions, "Raman effect" and "Raman lines" immediately followed. [90] [22] [91] In addition to being a new phenomenon itself, the Raman effect was one of the earliest proofs of the quantum nature of light. Robert W. Wood at the Johns Hopkins University was the first American to confirm the Raman effect in the early ...
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 ...
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.
Although the inelastic scattering of light was predicted by Adolf Smekal in 1923, [3] it was not observed in practice until 1928. The Raman effect was named after one of its discoverers, the Indian scientist C. V. Raman, who observed the effect in organic liquids in 1928 together with K. S. Krishnan, and independently by Grigory Landsberg and Leonid Mandelstam in inorganic crystals. [1]
Raman scattering discovered by Indian physicist C. V. Raman and Indian physicist Kariamanickam Srinivasa Krishnan, [17] providing basis for later Raman laser: 1928: Japanese engineer Kenjiro Takayanagi was the first to transmit human faces in half-tones on television, influencing the later work of Vladimir K. Zworykin [18] 1928
Raman spectroscopy is based on the observation of the raman effect which is defined as "The intensity of the scattered light is dependent on the amount of the polarization potential change". [61] The raman spectrum records light intensity vs. light frequency (wavenumber) and the wavenumber shift is characteristic to each individual compound. [61]
He is known to have been active during his retirement life in Bengaluru, involved with the compilation of research publications on Raman Effect and publishing a number of articles. During this period, he served as a visiting scientist at the National Aerospace Laboratories (1987–90)and was an Emeritus Scientist of the Council of Scientific ...
