In quantum mechanics, an energy level is degenerate if it corresponds to two or more different measurable states of a quantum system. Conversely, two or more different states of a quantum mechanical system are said to be degenerate if they give the same value of energy upon measurement.
States with the same energy are said to be degenerate. The degeneracy of an energy level is the number of states with that energy. The degeneracy of the \(J = 1\) energy level is 3 because there are three states with the energy \(\dfrac {2\hbar ^2}{2I}\).
If it is at a higher energy level, it is said to be excited, or any electrons that have higher energy than the ground state are excited. An energy level is regarded as degenerate if there is more than one measurable quantum mechanical state associated with it.
May 29, 2024 · In quantum mechanics, degenerate states refer to different quantum states of a system that have the same energy level. These states are said to be degenerate because, despite having different configurations or quantum numbers, their energy is identical.
Apr 28, 2023 · The \(J\)-th energy level of the three-dimensional rigid rotor is \(\left(2J+1\right)\)-fold degenerate; there are \(\left(2J+1\right)\) wavefunctions whose energy is \(E_J\).) We use doubly subscripted symbols to represent the wavefunctions that satisfy the molecule’s Schrödinger equation.
We show how the energies of the various states may change as the parameter λ is increased from zero. The two lowest energy eigenstates are non-degenerate and their energies can go up and down as λ varies. Next up in energy we have two degenerate states of H(0) (the Hamiltonian as λ = 0).
