The paper describes the results of a quantitative investigation of the intensity distribution within the rotational wings exhibited by a number of liquids. The characteristic features which are common to all liquids are a very large concentration of intensity in the close neighbourhood of the Rayleigh line and a relatively feeble, but defiuite, extension of the wing far beyond the limit expected on the basis of the existing theories. The effect of temperature on the intensity distribution is also studied and it is found that the above features continue to be present, practically unchanged, even at temperatures close to the boiling points of the respective liquids.
