M. Farhoud, S. Rajab Pasha and Atteh A. Al-Ghamdi
The molecular optical properties of a series of short-chain carboxylic acids group from formic to nonanoic acids have been analyzed using the electric and magnetic induced birefringence measurements. The linear and nonlinear optical parameters of the molecular liquids such as Scattering coefficients, molar electronic polarizability, contraction, mean polarizability, radius of molecule, optical polarizability, Verdet and Kerr constants have been calculated. The microscopic parameters of the molecular liquids such as anisotropic factors, optical anisotropy and orientation function have been calculated. Analysis of the results indicates for this series, the existence of a linear correction between molar Kerr constant, optical anisotropy and orientation function with carbon chain length have been found.
