Short abstract

This presentation conjectures and defends the idea of the existence of persistent electron current loops in diamagnetic molecules whose structures make it possible, from a purely geometric point of view, to associate a fixed axial vector with them (example: all molecules of the type O=C(XY), where X,Y are distinct atoms or groups). If the insight is correct then such molecules should possess an intrinsic spin and a permanent magnetic moment, thus enabling magnetic resonance phenomena similar to those associated with nuclides and giving birth to Molecular Magnetic Resonance (MMR). There is also a good chance that the overlooked persistent electron current loops represent a factor which presently hinders a forward leap of quantum chemistry methods such as DFT.
