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 …

Varian – 1D TOCSY. 1H – In a TOCSY spectrum, magnetization is allowed to pass from one proton to another that is 3 bonds or less away, and to take such steps repeatedly. Thus, magnetization moves from any one proton to all others throughout the spin system of which it is a part. The one caveat of this, is that the ...
