Abstract
Refractive index, molar refractivity and molar polarizability constant of heterocyclic compound such as Pyridoxine, Lincomycine have been studied in Ethanol, DMF, DMSO, and THF media at 303 K ± 0.10 C temperature and different concentration (0.625x 10-3 to 10.0x 10-3 M). The values of molar refraction (Rm) and molar polarizability (α) constant are found to be decreased with decreasing concentration of solute in solvent. Viscosity coefficient (A, B) evaluate by using jone-dole equation. These parameters throw the light on the solute – solvent interaction and solute – solute interaction.
