The Effects of Geometric Changes

This determinant leads of course to a non-bonding orbital with energy, a, confirming the (m — n) rule, but the wave function of this molecular orbital now has the following form  

This non-bonding orbital is illustrated in Fig. 3 for angles 0 = 90° — 54.73 . It is noteworthy that the overlap integral between and the ligand orbital V is zero i.e.. 

Clearly, as the hydrogen atoms move away from the original MH3 plane, the s and p orbitals mix to produce a nodal cone coincident with the M-H bond directions. In this way the non-bonding character is maintained. The computed s and p characters as a function of 0 are siunmarised in Table 3 for the situation where

The alternant nature of the non-bonding molecular orbital problem as represented in (5) means that the coefficients at the starred positions multiplied by the relevant resonance integrals must add up to zero at the unstarred position
