Abstract
IN his address describing the fundamental discovery of a new type of secondary radiation (Indian Journal of Physics, Mar. 31, 1928), Prof. Raman emphasised that the change of wave-length in light-scattering is observed not only in the cases of vapours and liquids, but also in crystals and amorphous solids; a block of ice, for example, showing the shifted lines in the scattered spectrum in approximately the same positions as liquid water. Glasses, on the other hand, show broad bands and not sharp lines. With the view of elucidating the influence of the state of molecular aggregation on the Raman effect, I have made a series of observations of the scattering of the light of the mercury arc in pure dry glycerine at various temperatures, and in glycerine—water mixtures of various strengths.
