Yet they were originally derived from crystal field theory, which contains a logical flaw; electrons on the magnetic ions are distinguished from those on the ligands. Thus there is a challenge: to replace crystal field theory with one of equal or greater predictive power that is based on a surer footing. The theory developed in this book begins with a generic Hamiltonian, OP - 268 CN - QC754.2.M333 SN - 9781400864461 SN - 1400864461 KW - Magnetic ions. KW - Crystal field theory.
