Long-range potentials have been calculated for 3He2 molecules dissociating to 3He 2 3S + 3He 2 3P, including the retarded dipole and the van der Waals interactions. Ultra-long-range wells with depths of up to about 2.4 GHz have been found in many of the adiabatic body-fixed potentials and rovibrational levels have been calculated for some of these wells, which have been found to support up to 4 rotationless vibrational levels.
