Symmetries of MOs in LCAO

(cf. Weissbluth [4] ch. 26.2). This leads to a classification of MOs according to their symmetry under symmetry transformations. The most important classes are the \bgroup\color{col1}$ \sigma$\egroup molecular orbitals which form \bgroup\color{col1}$ \sigma$\egroup-bonds, and the \bgroup\color{col1}$ \pi$\egroup molecular orbitals which form \bgroup\color{col1}$ \pi$\egroup-bonds, cf. Fig.
