Abstract
The Angular Overlap Model (AOM) is applied to the LaOX:Eu 3+(X = Cl, Br, I) series involving σ, π, δ and φ effects based on the experimental energy levels. The calculations are made in two cases. (1) Consider oxygen and halogen having the same bond-length. (2) Consider the real structure. In both cases, the results show that for σ -bonding parameters, the values of e σ decrease with increasing charge number of halogen, i.e. Cl − > Br − > I −, this indicates that the bonding ability also decreases with this order. The absolute values of each parameter are much larger than zero—therefore they all must be included in a practical analysis. In the second case, the values of the e x parameter are negative, which means a “back-bonding” is formed, and this is profitable for the formation of α-bonding, usually referred to as “synergic effect”.
