STUDIES ON THE DEPENDANCE OF OPTICAL, ROTATORY POWER ON CHEMICAL, CONSTITUTION. PART XXXVI. THE ROTATORY DISPERSION OF PHENYL-, o-, m- & p-TOLYL-IMINO- AND -AMINOCAMPHOR

The rotatory dispersion of phenyl-, o-, m- and p-tolylimino and amino-d-camphors in different solvents has been found to obey Drude's one-term formula, $[a]=\frac{k_0}{{\lambda }^2-{\lambda }_0^2}$ It is therefore ''simple".

The effect of solvents and of the position isomerism of the subitituent groups in the benzene ring on the rotatory power of these compounds has been discussed.

The effect of conjugated double bonds on the rotatory power, which is phenomenal in these series of compounds, as well as on the "characteristic^.' absorption band (${\lambda }_0$) is also discussed.
