Milloin ramansironta havaittiin ensimmäisen kerran?
Raman scattering or the Raman effect is the inelastic scattering of a photon by molecules which are excited to higher energy levels. The effect was discovered in 1928 by C. V. Raman and his student K. S. Krishnan in liquids, and independently by Grigory Landsberg and Leonid Mandelstam in crystals.
The effect had been predicted theoretically by Adolf Smekal in 1923.
