WebMay 1, 2024 · Figure 7.1.1. 11: The overall splitting is expressed as Δ t; the t stands for tetrahedral. However, sometimes it is useful to compare different geometries. In crystal field theory, it can be shown that the amount of splitting in a tetrahedral field is much smaller than in an octahedral field. In general, Δ t = 4/9 Δ o. WebElectron-pair Geometry versus Molecular Structure. It is important to note that electron-pair geometry around a central atom is not the same thing as its molecular structure.
