The Fourier Transform (FT) is an integral part of instrumentation used throughout chemistry. The FT is used in nuclear magnetic resonance, crystallography, infrared spectroscopy, and cyclotron mass spectrometry. Despite the wide spread use, often students do not have an intuitive understanding of the FT process. This poster seeks to improve the understanding of the FT through the analysis of a common signal (voices) using the Vernier interface and Microsoft Excel. The approach is appropriate for freshman chemistry laboratories or sophomore level laboratories.
