The authors consider the time dependent axially symmetric Schrödinger equation in spherical coordinates. They use a finite Fourier series in the polar angle, evaluating the coefficients by fast Fourier transform techniques. They show how to compute eigenvalues of the system and illustrate the accuracy of the method by comparing exact and computed values for a rigid rotor and a rigid dipole in a constant field.
