P. T. Narasimhan

[1] He was known for his studies on quantum-mechanical interpretation of magnetic resonance data[2] and his contributions in developing IIT Kanpur into a Centre of Excellence in academic research in the basic sciences.

[9] Narasimhan, who chose physical chemistry for his research for PhD, focused on the theory of nuclear spin coupling constants during his stint at Martin Karplus' laboratory; his mentor would go on to propound the Karplus equation which describes the correlation between coupling constants and dihedral angles in proton nuclear magnetic resonance spectroscopy.

[12] His contributions helped in the development of dynamic nuclear polarization at X-band in India, covering both the instrumentation and chemical applications.

[1] Some of the important contributions from Narasimhan were in the field of computational chemistry and the work of his research school at the IITK was reported to have pioneered the discipline in India.

His expertise in the field prompted the Institute of Nuclear Medicine and Allied Sciences to seek his assistance when they decided to establish one of the first magnetic resonance imaging facilities in the country which he successfully accomplished.

[4] His doctoral and masters students included Shridhar Ramachandra Gadre,[14] K. D. Sen, N. Chandrakumar, S Shankar, and Manvendra Krishna Dubey (MS 1979)[15] and he guided many researchers in their work.

[16][17] He organized an active research school at the Indian Institute of Technology, Kanpur featuring scholars from physics and chemistry departments which worked on the theoretical and experimental aspects of magnetic resonance.
