Note on the Chandrasekhar Model of the Optical Activity of Crystals

In this paper we discuss more wide applicability of the Chandrasekhar model of coupled oscillators in the optical rotatory dispersion of the crystals. We solve the problem using the Chandrasekhar model of two coupled oscillators in the case when we include all couplings between adjacent oscillators on the helix that is given by the crystal structure. Further we discuss the results of coupled oscillators models in the case of the including of the couplings between even and odd oscillators on the helix. The optical rotatory dispersion results obtained after the approximations of the oscillator strengths verify that these couplings have the important influence on the crystal optical rotatory dispersion.

Final Generalization of the Three Coupled Oscillator Model in the Crystal Optical Activity

In this paper we generalize the quantum mechanical model of three coupled oscillators because of its usage in the crystal optical activity. Using this model we can include the influence of all essential couplings between single oscillators which represent the molecules or atoms of optically active crystals belonging for example to the space groups of symmetry D(3,4) or D(3,6). The single oscillators are damped and therefore we can include both parts of the optical activity - optical rotatory dispersion and circular dichroism - into computations. We present more universal formulas for description of the above mentioned parts.
