Introduction One of the most important tasks that chemists are faced with is the separation and identification of compounds from mixtures. Gratifyingly, chemists have multiple tools in the quest to identify unknown organic compounds. Infrared spectroscopy is useful for determining functional groups that may exist in a molecule. NMR spectroscopy tells information about the connectivity of C-H bonds, as well as the numbers of and chemical environments of both carbon and hydrogen (as well as many other NMR active nuclei,...
