state), VE (vibrational excitation), and EE (electronic excitation) for simplicity. The ground state (GS) is the same as the highest occupied molecular orbital (HOMO) and the excited state (EE) is the same as the lowest unoccupied molecular orbital (LUMO). The energy of vibrational excitation states is found somewhere in between these orbitals.

USA Vibratory conveyor Google Patents

A vibratory conveyor arranged so that the vibrations have a substantially greater horizontal than vertical movement. More particularly, the vertical acceleration of material carried by the materialcarrying member is less than the acceleration of gravity and therefore the material conveyed does not physically leave the surface of the materialcarrying member.
