Determination of Alcohol Content in Alcoholic Beverages Using 45 MHz Benchtop NMR Spectrometer

Figure 1

1H NMR spectra of alcoholic products acquired with a 45 (a–d) and 400 (e–h) MHz NMR spectrometer. (a, e) Black Magic rum; (b, f) Smirnoff vodka; (c, g) Dr. McGillicuddy’s root beer liqueur; (d, h) Tour de Soleil Rosé. Triplet at 1.16 and quartet at 3.56 ppm correspond to hydrogens in methyl (CH3) and methylene (CH2) groups, respectively, in ethanol, while the singlet at 2.04 ppm corresponds to the methyl peak of acetic acid. Acetic acid CH3 peak was used for peak integration.
