Web2D NMR is an immensely powerful structural tool, but time-consuming. Targeting individual chemical groups by selective excitation in a 1D experiment can give the information required far more quickly. WebAug 28, 2024 · Theory. The chemical theory that underlies NMR spectroscopy depends on the intrinsic spin of the nucleus involved, described by the quantum number S. Nuclei with a non-zero spin are always associated with a non-zero magnetic moment, as described by Equation \ref{1}, where μ is the magnetic moment, \(S\) is the spin, and γ is always non …
