The simple harmonic oscillator has equally spaced eigenvalues that look like (n+1/2) ħ where is the angular frequency of the oscillator. Consider now the half-oscillator shown below, whose potential equals a regular oscillator for x > 0 and equals infinity (hard wall) for x < 0.

One-dimensional harmonic oscillator. The force of spring is . F=- k f x , thus its potential can be calculated as V x =- 0 x F d x' = 1 2 k f x .The Hamiltonian is then H =- ℏ 2 2m d 2 d x 2 + 1 2 k f x 2 , and its corresponding S.E. is - ℏ 2 2m d 2 ψ x d x 2 + 1 2 k f x 2 ψ x =Eψ x . We first change variable from . x to y = x / α where α = ℏ 2 m k f 1 4 .

Unlike the case of the harmonic oscillator, the potential term in the Hamiltonian for both the 2D and 3D rigid rotors is simply zero everywhere. There is no potential , V, that enters into the expression.
