Interpreting electron-nuclear-magnetic field interactions from a hamiltonian expressed in tensorial notation.
The general experimental hamiltonian expressed in tensorial notation is assessed in a way to ensure that the outcomes from such a hamiltonian reflect correctly the electron-nuclear-magnetic field interactions and yields the appropriate parameters. Without such knowledge the use of hamiltonians in tensorial notation to analyse magnetic resonance spectra may lead to questionable or even meaningless results reflected in several publications over the years. Furthermore, the errors that may occur in handling mixed hamiltonians compound the problem.
