Why is NMR spectroscopy useful?

Answer 1

Because it is a direct, non-sporting method of chemical analysis, that can directly lead to determination of structure, and of connectivity.

Of course, it has its limitations, but for the vast majority of organic compounds, #""^1H# and #""^13C{""^1H}# NMR spectroscopies can directly lead to a structural determination given melting points, and molecular weights. Clearly, this task is non-trivial, and regular chemical means of identification (i.e. boiling points, melting points of a few derivatives of known melting points) are required for unequivocal compound identification.

In ideal circumstances, organic mechanisms can be probed in real time; NMR spectroscopy thus offers a direct means to assess the extent of chemical reaction. Since the NMR experiment can be performed on mixtures, the organic chemist can also use this to assess the course of a reaction. Has the reaction worked; is the reaction complete or does it need more time?

Answer 2

Nuclear Magnetic Resonance (NMR) spectroscopy is useful because it provides detailed information about the structure, dynamics, and chemical environment of molecules. It can determine the connectivity of atoms within a molecule, identify functional groups, and analyze molecular symmetry. NMR spectroscopy is non-destructive and can be used to study samples in solution, solid-state, or even in living organisms. Additionally, it can be applied to a wide range of compounds, including organic molecules, inorganic compounds, proteins, and nucleic acids. NMR spectroscopy is widely used in chemistry, biochemistry, materials science, and medicinal chemistry for research, analysis, and characterization purposes.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
