(55753) Raman Main-belt Asteroid
Discovered on 13 September 1991 by Borngen, F., Schmadel, L. D. at Tautenburg.
Indian physicist C. V. Raman (1888-1970) showed the inelastic scattering of photons traversing a material. For his discovery of the so-called Raman effect he received the 1930 Nobel Prize in physics. The Raman spectroscopy helps to study atomic and complicated molecular structures.Naming citation (20030806/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
