Principles of Solid-State NMR Spectroscopy

The basic principles of solid state NMR spectroscopy can be most easily understood by discussing the relevant NMR interactions. In contrast to most other types of spectroscopy NMR has the unique feature, that the full quantum mechanical interaction Hamilton operators (Hamiltonians) of the spin system are usually known. As usual all energies are measured in units of the angular velocity (rad/sec), i.e. all energies are divided by ti.
