摘要：

The rotation-vibration Hamiltonian for a neutral diatomic molecule in an external magnetic field is established by appropriately transforming the pseudoseparated Hamiltonian to the molecular fixed frame. The partially screened Born-Oppenheimer approximation is subsequently performed. By explicitly investigating the dissociation limit of the molecule into neutral atoms we are able to identify the motional screening operator which is responsible for the screening of the nuclei by the electrons against: the magnetic field. A connection between the screening operator and the magnetic flux enclosed by the motion of the nuclei is established.
