Nmr of Red Bull Post Lab
Red Bull and Sugar Free Red Bull NMR Post Lab Report
Abstract
Viewed as one of the most significant tools in analytical chemistry, the Nuclear Magnetic Resonance (NMR) is a spectroscopy tool often used by chemists to determine the molecular profile – quality and quantity of the major components - of any given organic substance. Operating on basis of spectroscopy (study of the interaction between matter and radiated energy - Harris), the NMR can be either a one (1H NMR) or two (1H/13C NMR) dimensional spectral analysis that can be used identify and quantify the major components of a given substance by examining spectral patterns that derive from excitation of matter with radiated energy in the form of radio waves. In this experiment we will examine the spectral patterns derived from NMR scans of Red Bull and sugar-free Red Bull energy drinks. By examining the spectral splitting patterns of the major substance components as derived from experimental NMR scans against predicted spectrums, we will be able to identify both the quality and quantity of many of the major components of Red Bull and sugar-free Red Bull. As will be seen, some of the components of the two energy drinks will be identified with minimal difficulty. The experimental concentrations of DMSO, Caffeine and Sodium Citrate were 0.0014 M, 0.0021 M and 0.0017M respectfully for Red Bull and 0.0014 M, 0.0018 M and 0.0019 M, respectfully for Sugar Free Red Bull. The concentrations of the other major components of Red Bull and Sugar Free Red Bull were not obtained because analysis of those compounds required a higher degree of expertise than can be offered for this lab and will be identified by process of comparison, elimination and two dimensional spectral analysis where both protons and carbon 13 are examined to identify and quantify a compound that does not show up on a one dimensional NMR spectrum. This experiment will allow students to gain a better understanding of a Nuclear Magnetic Resonance,
