In the same year of 1928, two Indian scientists C. V. Raman and K. S. Krishnan were looking for the "Compton component" of scattered light in liquids and vapors. They found the same combinational scattering of light. Raman stated that "The line spectrum of the new radiation was first seen on 28 February 1928." Thus, combinational scattering of light was discovered by Mandelstam and Landsberg a week earlier than by Raman and Krishnan. However, the phenomenon became known as the Raman effect because Raman published his results earlier than Landsberg and Mandelstam did. Nonetheless, in Russian-language literature, it is traditionally called "combinational scattering of light".
