Born in 1888 in Tamil Nadu, Raman displayed an early fascination with science, which later translated into a remarkable career marked by curiosity, innovation, and perseverance. His research spanned various areas of physics, but he is most famously remembered for discovering the Raman Effect, which explains the scattering of light and its change in wavelength when passing through different materials.
This discovery revolutionized the study of light and molecular structures and earned him global recognition as the first Asian to receive the Nobel Prize in Physics in 1930. Today, CV Raman’s legacy is celebrated annually on National Science Day in India, inspiring generations of students and scientists to pursue scientific inquiry with passion and dedication. Beyond his awards, he is remembered as a symbol of India’s scientific prowess and a pioneer who placed Indian research on the global map.
CV Raman was born on 7 November 1888 in Tiruchirapalli, Tamil Nadu, into a family that valued education and intellectual curiosity. His father, a lecturer in mathematics and physics, played a pivotal role in nurturing Raman’s early fascination with the natural world. Growing up in an environment that encouraged questioning and learning, young Raman developed an insatiable curiosity about light, sound, and physics principles, laying the foundation for his future scientific pursuits.
Raman’s formal education began in the schools of Tiruchirapalli, where he quickly stood out for his academic brilliance. He later enrolled at Presidency College, Madras, one of the most prestigious institutions, earning his Bachelor’s and Master’s degrees in Physics. Raman’s exceptional intellect was widely recognized during college, culminating in a Gold Medal in Physics for his outstanding performance. His achievements reflected talent and a deep passion for understanding the laws of nature.
After completing his studies, Raman briefly joined the Indian Finance Department in Kolkata as an assistant accountant-general. Although this position provided stability, his heart remained with scientific research. His dedication to understanding the physical world eventually led him to leave his government job and fully commit to a career in science. This decision led to groundbreaking discoveries and global recognition, establishing him as one of India’s foremost physicists.
After leaving his government job in the Indian Finance Department, CV Raman dedicated himself entirely to scientific research. He joined the Indian Association for the Cultivation of Science (IACS) in Calcutta 1907. At IACS, he conducted pioneering experiments on the behavior of light and sound, establishing himself as a meticulous and innovative experimental physicist. During this time, Raman also mentored young researchers, inspiring many to pursue careers in science and laying the groundwork for India’s emerging scientific community.
In 1933, Raman transitioned to the Indian Institute of Science (IISc), Bangalore, as Director. At IISc, he emphasized rigorous experimental research and encouraged young scientists to explore original ideas. His leadership transformed IISc into a center of excellence in physics, attracting some of the brightest minds in India. Under his guidance, many students went on to make significant contributions to science, reflecting Raman’s dedication to education and mentorship.
Beyond his institutional roles, Raman was committed to strengthening India’s scientific infrastructure. In 1934, he founded the Indian Academy of Sciences, a platform for researchers to collaborate, publish findings, and promote scientific advancement nationwide. This initiative helped create a thriving scientific network and continues to support innovation and research today.
Later, in 1948, Raman established the Raman Research Institute in Bangalore, dedicated to advanced physics, optics, and acoustics research. The institute became a hub for experimental studies, where Raman and his team conducted pioneering work that further cemented his global reputation.
CV Raman’s career journey reflects his groundbreaking research and vision of nurturing talent, building scientific institutions, and creating a lasting impact on Indian science. His efforts ensured that India became a significant player in the global scientific community, inspiring generations of scientists to follow in his footsteps.
The Raman Effect is one of the most significant discoveries in physics. It reveals how light interacts with matter in unexpected ways. Discovered by CV Raman in 1928, this phenomenon involves the inelastic scattering of light. It provides a powerful tool for understanding molecular structures and revolutionizes chemistry, biology, and materials science research.
Before CV Raman’s groundbreaking work, scientists had long studied the scattering of light when it passed through different media. The prevailing theories suggested light scattered elastically, meaning its energy and wavelength remained unchanged. However, subtle anomalies in the scattering of sunlight through liquids hinted at phenomena that were not yet understood. Motivated by curiosity and a desire to explore these unusual patterns, Raman began investigating the behavior of light in more controlled laboratory conditions.
In collaboration with his colleague KS Krishnan, Raman conducted meticulous experiments using sunlight filtered through various liquids. Their work involved observing the scattered light at different angles and under precise conditions, allowing them to measure changes in the light’s properties. On 28 February 1928, Raman made a historic observation: the wavelength of scattered light changed, a phenomenon that the classical theories of elastic scattering could not explain.
This discovery, later named the Raman Effect, revealed that when light interacts with a material, a small fraction of the light is scattered inelastically, meaning it gains or loses energy corresponding to the vibrational modes of the molecules in the material.
The scientific significance of the Raman Effect was profound. It provided a new method to study molecular structures and interactions without destroying the sample. By analyzing the shift in wavelength, scientists could identify the chemical composition and properties of substances. The discovery quickly gained recognition from the global scientific community. In 1930, CV Raman was awarded the Nobel Prize in Physics, making him the first Asian to receive this honor in science.
The applications of the Raman Effect have been wide-ranging and transformative:
