The frequency difference between the incident radiation and the Raman Line is independent of the wave-length of the exciting radiation and coincides in magnitude with the infra-red absorption frequency of the molecule. [...] Soon after the discovery of the phenomenon of rotatory polaristion the first attempt to determine the mathematical form of the curves of the rotatory dispersion of quartz was made in 1817 by Biot 17 who showed that the rotatory power was inversely propotional to the square of the wave-length so that u = k/A2 AS En constant. [...] The spectrum which is formed in the spectrograph is divided into three horizontal strips corresponding to the three portions of the triple field and measurements of the rotatory power are made by observing the wave-length at which the three divisions of the spectrum lines are equally bright for a given setting of the analyser. [...] The rotatory dispersion is determined by giving two exposures the first in the absence of the active substance and the second with the latter in the apparatus.
