Abstract
CARRELLI, Pringsheim, and Rosen (Zeits. für Physik, 51, 511; 1928) have shown that the Raman scattering by water molecules yields only one modified frequency, corresponding to an infra-red band at 2.90µ. This modified frequency has, at first appearance, two anomalous aspects: (1) the modified ‘line’ is really a broad band of approximately 500 cm.-1 width, in contrast to the sharpness of Raman lines produced by organic liquids; (2) no infra-red band corresponds exactly with the centre of the observed scattered band, the nearest one being the strong 3.0µ infra-red band.
