Octahedral Site Stabilization Energy is the difference between the CFSE values in octahedral and tetrahedral geometries. And is denoted by OSSE. Octahedral Site Stabilization Energy is usually measured using the Diopter for Wave Number. Note that the value of Octahedral Site Stabilization Energy is always negative. Typically, the value of Octahedral Site Stabilization Energy lies in the range from 0 to 10000.
