Algebra and quantum geometry of multifrequency resonance

Abstract

A theoretical method for investigating the inter-relation between the electronic and molecular structures of 3 3 configuration ions in a tetragonal ligand field is established on the basis of the 120×120 complete energy matrices. Using this method, the local structure parameters of two tetragonal Cr 3+ centers in the NH4Cl:Cr 3+ system are determined. Furthermore, the relations between the molecular symmetry and the ligand field symmetry are discussed.
