Biography of R S. Krushnan
Name: R. S. Krishnan
Birth date: 23 September 1911
Thikaan: Thrissur, India
Wife: Narayani Krishnan
Business: Physicist, Scientist CSIR
Early Life of R S. Krushnan:
R. S. The full name of Krishnan was Rapal Sangameswaran Krishnan. R. S. Krishnan was an Indian experimental physicist and scientist. He was the head of the Department of Physics at the Indian Institute of Science and the Vice Chancellor of the Kerala University. Krishnan was born on 23 September 1911 in the small village of Rapal in Thrissur district, India. He received his early education from local schools.
He then did his BA Honors from St. Joseph's College Tiruchirappalli. He got the rank in 1933 for this. In 1941, he received his PhD from Cambridge University. CV Raman and Norman Feather were his doctoral advisors. He was married to Narayani Krishnan.
Works of R S. Krushnan :
In 1938, he worked as a researcher under the Sir John Cockrant in the Cambridge University's Cambridge Laboratory. His research has supported the development of cyclotrons and the observation of deuteron-induced fission in uranium and thorium. In 1942, Krishnan joined the Physics Department of the Indian Institute of Science, Bangalore. In 1948, he served as the head of the Department of Physics, till 1972.
In 1973, Krishnan became the Chancellor of Kerala University, Thiruvananthapuram. He worked there till 1977. Even after his retirement, he has worked as a visiting scientist at National Aerospace Laboratories from 1981 to 1990.
Further working on the Raman effect, Krishnan has done an important job of finding the reciprocal relationship between the intensity of the horizontally dispersed light scattered with horizontal rotation despite the colloidal particles. It is also known as the Krishnan reciprocity effect. Not only this, but Krishnan is credited with the second order Raman spectra in diamonds and in the Alkali helid.
Kashan has done many experiments such as diamond crystalline and fused quartz alumina and alkaline halide in braillein scattering. He was the first scientist to do such experiments. Krishnan also documented investigations on thermal expansion, elastic constants, and photoelastic constants of sphatico.
Attempts were made by Krishnanavada on the detetting of Indian rock formations using atomic geological techniques. Krishnan worked as an international committee on ferro electricity. He represented India at international conferences and seminars for conferences on Raman spectroscopy. Krishnan was an Emeritus Scientist of CSIR.
