Abstract

STUDENTS of diatomic molecules and of related systems have long used the Morse potential function1 where x is the stretch of the interatomic bond (with V=0 at the equilibrium configuration x=0), D is the dissociation energy, and a a constant parameter. For energies less than D and no rotation, Morse gave the quantum energy levels of (1), namely where ν0≡(a/2π)(2D/µ)½ is the frequency of classical small vibrations, µ being the reduced mass of the two bonded atoms.
