"Sir CV Raman's work finds extensive application in diverse areas, even quantum chemistry - in which Chancellor Merkel holds a doctorate," Modi tweeted.
"Terms Raman Effect and Raman Spectrum themselves were coined in 1928 by a German physics professor Dr Peter Pringsheim," he said.
Two of the scientists who nominated Raman for the Nobel Prize were German physician Richard Pfeiffer and German physicist Johannes Stark who had won the Nobel in 1919.
The seeds of Indo-German research collaboration were sown in Raman's time. Such collaboration has grown immensely over the years and now Germany is one of India's leading partners in research.
