C.V. RAMAN'S STUDENT SUKUMAR CHANDRA SIRKAR: LIFE AND SCIENCE

摘要

Dr. Rajinder Singh has made a very valuable contribution in writing a book on the Life and Science of Dr S C Sirkar who did his doctoral work under the supervision of the Nobel Prize winning physicist Dr C V Raman at Indian Association for the Cultivation of Sciences (usually abbreviated as IACS), Kolkata. Raman effect was discovered in 1928 and at that time, there were 28 scholars working with C V Raman and only 2 of them (S C Sirkar and K S Krishnan) were working on Light Scattering. Although K S Krishnan did not share the Nobel Prize with Raman (many thought he should have), but Krishnan did get good recognition of his work. However, as mentioned by Dr. Rajinder Singh, although Sirkar had contributed significantly to the discovery of Raman effect, he remained the unsung student of Raman. In 1930 (less than 2 years after the discovery of the Raman Effect), Sirkar had analyzed the intensity dependence of Raman lines which, according to Professor Kankan Bhattacharyya, laid the foundation of Resonance Raman Spectroscopy. This is indeed a remarkable contribution of Dr Sirkar which has been brought out by Dr. Rajinder Singh. Indeed Sirkar was awarded the DSc degree of Calcutta University for his work in determining the relative intensities of Raman lines.
