The dielectric parameters of paracetamol for four different temperature (30°C, 40°C, 50°C and 60°C) at a microwave frequency 9.265 GHz have been observed in the dilute solutions of carbon tetrachloride with the help of X-band microwave bench. The dielectric parameters like dielectric constant (ε'), dielectric loss (ε''), static permittivity (ε0) and optical permittivity (ε) are calculated for five different weight fractions of paracetamol in the dilute solutions of carbon tetrachloride. The values of ε0 and ε are calculated by using Dipole meter and Abbe's refractometer. The analysis shows that the values of dielectric parameters increase with the increase in the weight fraction of paracetamol whereas these values decrease as the temperature increases. This study suggests that there are both intermolecular and intramolecular orientation exist in the solutions .
