The Nuclear Magnetic Resonance (NMR) is introduced to students during Organic Chemistry. The NMR is typically used for qualitative and conformational analysis of a compound to determine the structure. The Instrumental Analysis lab uses the PerkinElmer FT-IR Spectrometer to quantify ethanol found in a sample of Skyy Vodka. For this study, an experiment was developed to use quantitative functions of the NMR to similarly quantify ethanol samples. The concentration of alcohol in Skyy Vodka was quantitatively analyzed by using a program called Eretic found in the Bruker NMR software. Eretic is used to quantitatively analyze a proton NMR to define the concentration of ethanol in the reference sample to be compared to the unknown concentration of ethanol in the sample. The analyzed data from the NMR will be compared to the analyzed data from the IR to see how accurate the NMR method is in quantifying ethanol found in the sample.
