Abstract:	We prove results about vanishing and nonvanishing of radial dipole matrix elements $D_{n,l}^{n',l'} = leftlangle {n',l\|r\|n,l} rightrangle$ for certain classes of spherically symmetric potentials. A basic tool is a new sum rule based on Ehrenfest's law and the superposition principle for solutions of the Schrödinger equation.
