“…The values of 9% were determined from the measurements of the rotation angle y of the plane-polarized light propagating along the optical axis using the relation y = ng,/n,M, where no is the ordinary refractive index. The measured values of the rotatory power Q = v / d along the optical axis agree well with those obtained in [3].…”

“…Though the structure of the compound has no pronounced anisotropic features [Z], CdP, appears to be greatly birefringent and exhibits considerable rotatory power along the optical axis [3]. Therefore, an interest in the magnitude and spectral dependence of the optical activity effects in other, more general crystallographic directions arises.…”

Spectral dependences of the gyration tensor components gll, gas, refraction indices and birefringence of tetragonal CdP, are investigated a t 300 I<. The optical activity of the crystal is found to be determined by both the crystal and the molecular contributions, the latter being due to the distortion of the tetrahedral symmetry of the structural elements. The dispersion of the refractive indices is discussed on the basis of a single-effective-oscillator model. The ionicity of CdP, is equal to 0.5B and is close to the values of AIIBVI compounds and the ionicity of Cd-P bond in AI1BrVCT semiconductors. The dispersion of the spectroscopic properties of CdP, is concluded to be mainly determined by the Cd-P bound. HemB Tnna AIIBVI, a TaKme c~m e i i Cd-P B nonynpoBonmKax AIIBIVCZ. ~~K J I I~Y~~T C H

The refined results of the specified dispersion of refractive indexes, birefringence, optical activity of anisotropic fl-CdP2 single crystals and the components of both the gyration tensor G33 and the optical activity tensor 7123 in a wide spectral band of polarized light under normal conditions are presented. The influence of temperature and radiation intensity of neodymium and ruby lasers on these characteristics of CdP2 single crystals is studied and analyzed.

The natural optical activity (NOA) and the refractive index are measured in the temperature intervals of 4.2 to 400 K and of 293 to 400 K, respectively. The dispersion of the NOA is best approximated by a single-term Drude formula. The parameters of dispersion formulas are given for various temperatures. A temperature dependence of NOA in CdP, is found. The temperature variation of the CdP, rotational ability is shown to be mainly due to the temperature shift of the corresponding optically active band at E = 2.4 eV. I n the 360 to 380 K temperature range a break is observed in the temperature dependence of the specific rotation and the refractive index, while the temperature dependence of the gyration tensor component displays a characteristic feature with well defined maxima, which indicates the presence of a phase transition in CdP, crystals in this temperature range.Die natiirliche optische Aktivitiit (NOA) und der Brechungsindex werden in den Temperaturbereichen 4,2 bis 400 K bzw. 293 bis 400 K gemessen.
