Atomic orbitals of this mixed type are usually referred to as hybrids (or more specifically digonal s-p hydrids). As with the one-dimensional model, they reinforce on one side of the nucleus and partly cancel on the other. Hence the transformation is from the delocalised s and p description to a description in terms of two equivalent orbitals, localised on opposite sides of the nucleus. Again a similar transformation may be applied to a 4 X 4 determinant describing a system with two electrons in each of these orbitals. [Pg.185]

Hybrid orbitals. Atomic orbitals obtained when two or more nonequivalent orbitals of the same atom combine. (10.5) Hybridization. The process of mixing the atomic orbitals in an atom (usually the central atom) to generate a set of new atomic orbitals. (10.4) [Pg.1046]

As pointed out in the text, orbital hybridization or orbital mixing is not an actual physical phenomenon—it is a mathematical process of transforming pure atomic orbitals for isolated atoms into new atomic orbitals for bonded atoms. In particular, a hybrid atomic orbital is the result of a mathematical combination (algebraic addition and subtraction) of the wave functions describing two or more atomic orbitals. When the algebraic functions that represent s and p orbitals are added. [Pg.476]
