Abstract

We investigate the interaction of molecular electronic states through nuclear motion in the presence of a homogeneous magnetic field. The different possibilities and effects of this interaction are classified according to the symmetries and the qualitative behavior of the diabatic energy curves. As a central result we show that conical intersections of electronic energy potential surfaces, which are in the field-free case common for polyatomic molecules, appear in the presence of a magnetic field already on the level of a diatomic molecule.
