dc.description.abstract
We calculate the energy levels of a coupled-rotors model that has proved useful for the analysis of the multiple tunnelling peaks in the inelastic neutron scattering from 4-methylpyridine crystals. We resort to the Rayleigh–Ritz variational method with a basis set for each irreducible representation. The energy levels in terms of the rotor coupling strength exhibit a rich pattern of crossings between states of different symmetry and avoided crossings between states of the same symmetry.
