The Revised Quantum Mechanical Theory of the Optical Activity of Crystals

In this paper we present the revised view on the optical activity of crystals based on the model of two dumped coupled oscillators. The results are compared with the results of the same problem solved before and it is presented that the results of the quantum mechanical model are the generalization of the classical model only and they do not introduce the new terms of quantum mechanical nature. The results are discussed with regard to the rotational strengths of normal modes of vibrations and the formula for the complex rotatory power containing the rotational strengths is presented.

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.
