Multiplying each character in this row by the corresponding
character in the row for the A2’’ representation in the D3h
character table (Table 4.1) gives the unnormalized form of
the wavefunction for the a2’’ LGO (equation 4.22). Simplification
and normalization gives equation 4.23. The a2’’ LGO
can thus be described as an in-phase combination of 2pz orbitals
and is shown schematically in Figure 4.22 as LGO(5).
