The discrete energy spectra of composite inverse power-law binding potentials of the form with
are studied analytically. In particular, using a functional matching procedure for the eigenfunctions of the radial Schrödinger equation, we derive a remarkably compact analytical formula for the discrete spectra of binding energies
which characterize the highly excited bound-state resonances of these long-range binding potentials. Our results are of practical importance for the physics of polarized molecules, the physics of composite polymers, and also for physical models describing the quantum interactions of bosonic particles.
