Abstract

Objectives: To study the effect of molecular interactions present in ternary system on refractive index with respect to different concentration. To evaluate the optical parameters by examine the change in refractive index. Methods: The compound under study was synthesized and purified by recrystallization. DMSO used for preparation of different series of concentration was purchased as analytical reagent grade (AR) of minimum assay of 99.9%. Different concentration was prepared from stock solutions. For density measurement we have adopted used calibrated pycknometer. To measure refractive index we have used Abbes Refractometer (AR-56, COSLAB). For maintaining required desired temperature we have continuously circulated water through refractometer. Findings: In this article, we are reporting the measurement of density, refractive index, molar refraction and polarizability constant as function of temperature at different concentration. We found that density has inverse relationship with temperature which can be well explained with respect to molar volume effect. Moreover, refractive index also declines with rise in temperature due to weakening of solute-solvent and solute-solute interactions. Due to this optical property related to refractive index are found to change. Novelty: Work reported in this article is not studied earlier. Our work with study of refractive index in ternary mixture system helps to understand the electronic component of radiation with the molecules.
