FIG. 9.1 The one-dimensional particle on a ring system (1DPR) is one dimensional in rotation angle (θ) but two dimensional when considering the xy plane that it occupies. More about this image found in The one-dimensional particle on a ring system (1DPR) is one dimensional in ...

FIG. 9.2 Visual representations of the 1DPR wave functions—the ring harmonics. The imaginary part depends upon the sign of the quantum number and is typically interpreted to indicate the direction of rotation. The real parts are unchanged with the sign of the quantum number and are used More about this image found in Visual representations of the 1DPR wave functions—the ring harmonics. The i...
