INDEX sulfur ligands

The theory of stationary ENDOR transition frequeneies is well understood. In the framework of metalloprotein applications we consider one metal ion (or more) in the center of a coordination sphere in which ligands like protons and nitrogen nuclei are in interaction distance with the ion. Shown in Figure 1 are sketches of three different iron-sulfur clusters in proteins and their immediate environment that are of relevance for the present report. The Spin Hamiltonian applicable to this situation contains metal ion terms indexed as M and ligand terms (indexed L) ...
