How high is high and how low is low? With respect to transition‐metal complexes of different coordination numbers and stereochemistry, high‐, low‐, and intermediate‐spin states may mean different things. The hybridization of the d orbitals, similar to the deformation of a balloon subjected to pressure (see picture), provides a rationale for the splitting of the d manifold and, hence, for the allowed spin states in a given complex.
