Abstract	Impedance spectroscopy is a method of modeling materials with equivalent circuits to determine electrical properties, such as the resistivity and the dielectric constant. We explore impedance spectroscopy, both theoretically and experimentally through applying the method to samples of BaCuS1-xSexF. Grain boundary effects were dominant in the results, and although they prevented us from determining the resistivity and dielectric constant of the bulk material, we gained valuable knowledge about the limits of the samples in question and limits on the impedance spectroscopy method. We discovered that although modeling the electric properties of samples with impedance spectroscopy is difficult, it is a versatile theory with many applications.
