Calculations of Energy Levels and Magnetic Parameters

There are complementarities in energy levels of the Oh- and Id-references, as shown in Table 29. The ground terms of the tetrahedral dn systems match those of the octahedral dw n systems. Note that the CF strength is considerably reduced for tetrahedral complexes relative to octahedral ones At = - (4/9)A0.
