A simple procedure for derivation of octant rules for optically active molecules containing a chromophoric group is developed within the framework of Kuhn's classical model of coupled oscillators. The important feature in this derivation is the clue that the locus of the center of gravity of the atoms not belonging to the chromophoric group and the direction of maximum polarizability of this ensemble of atoms are not independent. The octant rule for carbonyl compounds arrived at by this procedure is in agreement with the empirical one. A newly derived rule for cis-azo compounds is verified by empirical data.
