Abstract
Optical induced birefringence is used, as a sensitive method, to study intermolecular interactions and to obtain microscopic parameters of two
analogous groups of viscous liquids. In order to obtain the effect with high efficiency, an experimental setup has been modified. This modification was concerning the reduction of the state of polarization distortion produced from the passage through beam splitters. The first group of the liquids studied was
polyethylene glycol; the chain length of which was changed and its influence
on the optically induced birefringence was obtained. The other group was a
set of analogous diols. Each member of this set has the same main structure with different heteroatom. The influence of the heteroatom on the optically
induced birefringence was studied. The dependence of the induced
birefringence for all liquids under study on the temperature was also studied.Different concentrations of all pure liquids with methanol as a common solvent have been prepared and studied carefully using the optical Kerr effect. Also, the temperature of each concentration has been varied and the optical induced birefringence has been studied for all solutions of the liquids under investigation. Optical Kerr effect proved that it is a very sensitive method to study microscopic parameters and the structure of monomers and polymers.
