C.V. Raman Chandrasekhara Venkata Raman was born in 1888 in a village in southern India. As a child, Raman was precocious, curious and highly intelligent. His father was a college lecturer in mathematics, physics and physical geography, so the young Raman had immediate access to a wealth of scientific volumes. By the age of 13, he had read Helmholtz’s Popular Lectures on Scientific Subjects. Raman was deeply interested in music and acoustics. While in college, he read the scientific papers of Lord Rayleigh and his treatise on sound as well as the English translation of Helmholtz’s The Sensations of Tone. This initiated Raman’s later interest in the physics of drums and stringed instruments such as the violin. He used fine-chalk powder and photography to investigate the vibrational nodes of drums; the white chalk remained only at the nodes of the vibrating membrane. In a culturally anomolous and brazen act, when Raman was 18, he arranged his own marriage to Lokasundari (later called Lady Raman), a 13-year-old woman from Madras. The two then moved to Calcutta, where Raman accepted a position in the Indian Finance Department. During the next ten years—from 1907 to 1917—he struggled to balance his well-paying government job with his drive to be a scientist. When he wasn’t at the Finance Department, he was conducting experiments at the Indian Association for the Cultivation of Sciences (IACS) in Calcutta. The IACS had been formed along the pattern of the Royal Institution in Lo...

Lived 1888 – 1970. C. V. Raman discovered that when light interacts with a molecule the light can donate a small amount of energy to the molecule. As a result of this, the light changes its color and the molecule vibrates. The change of color can act as a ‘fingerprint’ for the molecule. Raman spectroscopy relies on these fingerprints. It is used in laboratories all over the world to identify molecules, to analyze living cells without harming them, and to detect diseases such as cancer. Advertisements Beginnings Chandrasekhara Venkata Raman was born on November 7, 1888 in the city of Trichinopoly, Madras Presidency, British India. Today the city is known as Tiruchirappalli and sits in the Indian state of Tamil Nadu. Raman’s father was Chandrasekaran Ramanathan Iyer, a teacher of mathematics and physics. His mother was Parvathi Ammal, who was taught to read and write by her husband. At the time of Raman’s birth, the family lived on a low income. Raman was the second of eight children. Raman’s family were Brahmins, the Hindu caste of priests and scholars. His father, however, paid little attention to religious matters: Raman grew up to share his father’s casual attitude to religion, but he did observe some Hindu rituals culturally and respected traditions such as vegetarianism. When Raman was four years old his father got a better job, becoming a college lecturer, and the family moved to Waltair (now Visakhapatnam). From a very young age Raman was interested in science, readi...

C.V. Raman was awarded the 1930 Nobel Prize in Physics for his discovery of the C.V.

Raman was knighted in 1929, and in 1933 he moved to the Indian Institute of Science, at Indian Journal of Physics and the Indian Academy of Sciences, and trained hundreds of students who found important posts in universities and government in India and Myanmar (Burma).

Designated December 15, 1998, at the Indian Association for the Cultivation of Science in Jadavpur, Calcutta, India. "I propose this evening to speak to you on a new kind of radiation or light emission from atoms and molecules." With these prophetic words, Professor C. V. Raman of Calcutta University began his lecture to the South Indian Science Association in Bangalore on March 16, 1928. Raman proceeded to describe a discovery that resulted from a deceptively simple experiment. Conducted far from the great centers of scientific research in the Western world, the results would capture the attention of scientists around the world and bring many accolades, including the Nobel Prize, to their discoverer. Contents • • • • • • • • • Educated entirely in India, C.V. Raman made his first trip to London in 1921, where his reputation in the study of optics and especially acoustics was already known to the English physicists J. J. Thomson and Lord Rutherford, who gave him a warm reception. Raman's specialty had been the study of the vibrations and sounds of stringed instruments such as the violin, the Indian veena and tambura, and two uniquely Indian percussion instruments, the tabla and the mridangam. But it was the return trip from London to Bombay aboard the SS Narkunda that would change forever the direction of Raman's future. During the fifteen-day voyage, his restless and probing mind became fascinated with the deep blue color of the Mediterranean. Unable to accept Lord Raylei...

Can you imagine what it might be like to be the first person from your country to win the Nobel Prize? What about the first person from your race or even continent? If you can, you might have some idea of what life was like for C.V. Raman! Born in 1888 into an academically minded family in India, Chandrasekhara Venkata Raman would go on to surpass the achievements of his professor father by becoming the first Asian to receive the Nobel Prize in physics. The second of eight children, C.V. was the son of a college professor. His father, Chandrasekaran, taught math, geography, and physics. He encouraged all of his children to excel in academics, and young C.V. finished his traditional schooling at the age of eleven. Raman would complete both his bachelor's and master's degrees in physics before he turned 20. His early graduations were quite an achievement, even by today's standards. Raman would discover what is known today as the Raman effect, which helps to explain why certain molecules cause waves of radiation to scatter differently than other molecules. While traveling to Europe in the early 1920s, C.V. noticed that glaciers had a blue color and was intrigued. He wanted to find out what the cause of the blue coloration was and would go on to analyze how water molecules scatter light in an attempt to explain the situation. These experiments would lead him to be interested in how other materials might interact with light, or other types of electromagnetic waves. At the time,...

His father was a lecturer in mathematics and physics so that from the first he was immersed in an academic atmosphere. He entered Presidency College, Madras, in 1902, and in 1904 passed his B.A. examination, winning the first place and the gold medal in physics; in 1907 he gained his M.A. degree, obtaining the highest distinctions. His earliest researches in optics and acoustics – the two fields of investigation to which he has dedicated his entire career – were carried out while he was a student. Since at that time a scientific career did not appear to present the best possibilities, Raman joined the Indian Finance Department in 1907; though the duties of his office took most of his time, Raman found opportunities for carrying on experimental research in the laboratory of the Indian Association for the Cultivation of Science at Calcutta (of which he became Honorary Secretary in 1919). In 1917 he was of...

This occurs, for example, when light packets—photons—encounter molecules in a gas. In 1928 Venkata Raman discovered that a small portion of the scattered light acquires other wavelengths than that of the original light. This is because some of the incoming photons’ energy can be transferred to a molecule, giving it a higher level of energy. Among other things, the phenomenon is used to analyze different types of material. To cite this section MLA style: Sir Venkata Raman – Facts. NobelPrize.org. Nobel Prize Outreach AB 2023.
