Symmetry quantum mechanics
Web88 Groups and Representations in Quantum Mechanics i.e., the two representations are equivalent.Suppose that this represen-tation is reducible. Then there is a unitary transformation of the ’ j such that there are two or more subsets of the ˆ i that transform only among one another under the symmetry operations of the Hamiltonian. Webthe Hamiltonian has Rotational Symmetry . This is true for the coulomb (and gravitational) potential as well as many others. We know from classical mechanics that these are important problems. If a the Hamiltonian has rotational symmetry, we can show that the Angular Momentum operators commute with the Hamiltonian.

That’s why it’s a centre of symmetry. On the other hand, note that classifying orbitals just by g and u does not make much sense. You should always consider the entire molecule’s point group and thus always consider which (set of) irreducible representation(s) an orbital or a …
