Note on the theory of the rotatory dispersion of crystals

The refined results ofthe specified dispersion ofrefractive indexes, birefringence, optical activity of anisotropic fi -CdP2 single crystals and the components ofboth the gyration tensor G33 and the optical activity tensor r 123 in a wide spectral band of polarized light under normal conditions are presented. The influence oftemperature and radiation intensity ofneodymium and ruby lasers on these characteristics of CdP2 single crystals is studied and analyzed.

“…One can mention traditional methods enabling the derivation of the dispersion relations for the description of the crystalline OA in the direction parallel to the optic axis. Let us mention the method of two coupled oscillators [6][7][8] or the theory of excitons [9] at least. However, the theory of coupled oscillators can provide more general relations for the OA dispersion than any other method.…”

In the past, Chandrasekhar’s method of two coupled oscillators was successfully used for the interpretation of crystalline optical activity. The optical activity dispersion relations were obtained in the direction of the optic axis and also in the direction perpendicular to the optic axis. However, Chandrasekhar’s approach to the solution method is based on a mistake in his calculations. This mistake does not influence the character of the dispersion relations in the direction of the optic axis, which was proved by the solution of the model of coupled oscillators using the Condon relations. Similar conclusions have not been introduced for the direction perpendicular to the optic axis. For that reason, the model of coupled oscillators, using the Condon relations, is presented also for the direction perpendicular to the optic axis. The considered model of coupled oscillators is more complicated and therefore corresponds to the structure of real crystals more closely. It can be proved that, in spite of Chandrasekhar’s mistake in the calculations, his conclusions hold. The character of the dispersion relations in the directions parallel and perpendicular to the optic axis is the same and differs only by a constant multiplicative factor. However, Chandrasekhar’s factor differs from the derived form of this factor, which is presented in this paper. It is also presented for the example of an atomic crystal of tellurium that the form of Chandrasekhar’s factor is incorrect. The mistakes in Chandrasekhar’s derivations are also discussed.
