Attention is called to the desirability of obtaining intensity data for Raman lines which would permit quantitative comparisons between laboratories using different apparatus. A simple method for obtaining such data is possible by using the $459cm-1$ line of $CCl4$ as a reference and by eliminating the spectrometer and detector properties by calibrating with the radiation from an incandescent lamp, standardized as Illuminant A by the National Bureau of Standards.
