C. L. Khetrapal, born on 25 August 1937 in the Indian state of Uttar Pradesh, did his college studies at the Allahabad University from where he graduated in 1957 and completed his master's degree in 1959.[6] He started his career by joining the Atomic Energy Establishment Training School, Mumbai the same year, simultaneously doing his doctoral research at Mumbai University to secure a PhD in 1965. In between, he worked at the Tata Institute of Fundamental Research for a while and moved to Switzerland where he did his post-doctoral studies at the University of Basel from 1967 till 1969. Then he shifted his base to the US to work at the Liquid Crystal Institute of Kent State University as a research assistant. He returned to India in 1973 and joined the Raman Research Institute as an assistant professor where he spent over eleven years till his move to the Indian Institute of Science as a professor and the head of the Sophisticated Instruments Facility in 1984. On his superannuation from service in 1998, he was appointed the vice chancellor of the Allahabad University.[1] When his tenure ended in 2001, he joined the Sanjay Gandhi Postgraduate Institute of Medical Sciences as a distinguished professor for a five-year term (2001–06) and also held the directorship of Centre of Biomedical Magnetic Resonance, Lucknow, an autonomous research centre of the Government of Uttar Pradesh. In between, he had two stints at the National Institutes of Health as a visiting scientist during 1979–80 and in 1984.[3]
Legacy
Using nuclear magnetic resonance spectroscopy (NMR), Khetrapal studied the molecular orientation in the nematic phase of liquid crystals, the non-planar distortions in peptides in the liquid phase and weak molecular interactions involved in hydrogen bonding.[7] Apart from pioneering NMR studies in India, he established the Institute of Interdisciplinary Studies and the Institute of Professional Studies at Allahabad University.[3] His contributions are also reported to be behind the establishment of the National Centre on NMR in Bangalore. He has published a number of articles and books, besides contributing chapters to books published by others including the 8-volume Encyclopedia of Nuclear Magnetic Resonance.[8] He was one of the founders of the National Magnetic Resonance Society and the Centre of Biomedical Magnetic Resonance and served as the first president of the former and was an incumbent director of the latter.[3]
