Quadrupolar 300 INDEX

The theoretical approach will take use of these operators. The effective Hamiltonian will be described for a single site, site v, but for simplicity the formalism omits the index v unless it is absolutely necessary as the expressions are equivalent for all sites in the N-site jump process. For a system including both CSA-and quadrupolar interactions, the effective Hamiltonian for a single site during a pulse is...
