Abstract: A study of the relaxation times of some polar solvents was carried out using the Cole-Cole relaxation model. The solvents; Methanol, Ethanol, Butan-1-ol were studied. The study was carried out within a frequency range of 100kHz and 50MHz and a temperature range of 100C and 500C. The following relaxation times: 0.09273 ns, 0.04073 ns, 0.03138 ns, 0.02082 ns and 0.01439 ns for methanol; 0.9360 ns, 0.6132 ns, 0.4031 ns, 0.2713 ns and 0.1812 ns for ethanol and 0.2385 ns, 0.1931 ns, 0.1424 ns, 0.1059 ns and 0.0796 ns for butan-1-ol at 10OC, 20OC, 30OC, 40OC and 50OC respectively were deduced using the slopes of the graphs plotted from the derived equation. The linear fit of the plotted points converged at the origin. The R2 values for each solvent under investigation, fitted perfectly. This eliminates the need for elaborate experimental analysis. As the temperature increases, the relaxation time decreased. These results can be used in drug design and synthesis at radio wave frequency range.
