The possession by photons of intrinsic angular momentum is further strikingly confirmed by investigations of light scattering in liquids. The spin theory indicates diminution of rotational scattering to half the value given by classical considerations. Spectroscopic measurements of the depolarisation of scattered light, using broad and fine slits, furnish a convenient test. Observations by Venkateswaran with carbon disulphide and benzene liquids quantitatively confirm the predicted results.
