WebIf it happens that the square root in Equation 7.33 vanishes, then the degeneracy is not lifted at first order. In this case, diagonalizing the W matrix puts no restriction on α and β and you still don’t know what the “good” states are. If you need to determine the “good” states—for example to calculate higher-order corrections—you need to use second-order … WebAnswer: Solving for the states of a symmetric molecule or a symmetric solid, you are really only solving a small part of the problem to get to the total solution, because the rest of the problem is solved by exploiting symmetry.

The degeneracy in a quantum mechanical system may be removed if the underlying symmetry is broken by an external perturbation. This causes splitting in the degenerate energy levels. This is essentially a splitting of the original irreducible representations into lower-dimensional such representations of the perturbed system.
