The temperature dependence of the polarizability tensor components α || 1, α⊥ 1 and new quantity ∑(ri)² were investigated for homologue of CBn liquid crystals, For ache liquid crystal the new quantity ∑(ri)² was found for two temperature like the transition temperature to the solid state Tc and the transition temperature to the liquid TO. Both functions ∑(ri)²TC and ∑(ri)²TO are linear function of...
The method of calculation of kA coefficient needed for calculation of polarizability tensor components α[równoległa] and α(prostopadła] of liquid crystal molecule is presented. Having a refractive indices ne and no, density d, molecular weight M and kA we can calculate the polarizability anisotropy (α[równoległa]-α[prostopadła]), polarizability tensor components α[równoległa]1, α[prostopadła]1 and...
Two phenomenon influence temperature dependence of components of polarizability tensor. The first one the change of distance between electron proton with temperature. The second is the conformation change of molecule. From the two reasons mentioned above the electron proton distance change is only the linear function of temperature. It gives the possibility of separation of two part of αII and α ⊥...

The polarizability tensor components α II, α ⊥, polarizability anisotropy (α II - α ⊥) and (ne+no) / d of five liquid crystals CB 6, CB 7, CB 8, MBBA and EBBA are investigated in order to check how the addition of CH2 group to the molecule influence on the values of its polarizability anisotropy (α II - α ⊥) and (ne+no)/d. Obtained results show that the addition of CH2 group change mentioned above...
