New experimental data on the density, sound velocity, isentropic and apparent molal compressibility of selected BADs + DPPH● solutions as a function of temperature and concentration are reported. The results are discussed with regards to structure-activity relationship (SAR) principles of BADs. The relative deviations in RSAs varied with structural potentials of BADs which were analyzed by making a comparative study for both the spectrophotometric and physicochemical results.展开更多
