APPROXIMATE ROTATIONAL QUANTIZATION AND THE PAULI PRINCIPLE

Approximate rotational quantisation is associated with imperfectly def ined wavenumber and imperfect angular momentum conservation of a rotor interacting with its environment. Standard theories of hindered molec ular groups like CH3 allow only perfect quantisation. We show that thi s is because they attribute two incompatible sets of properties to the nuclei of hydrogen atoms in a false version of the Pauli principle an d are thereby restricted to a closed space inconsistent with environme ntal interaction. They conclude that environmental dynamics is constra ined to preserve the perfect quantisation. The true Pauli principle is consistent with an open space and leads to approximate quantisation w ithout symmetry constraint and to similarity with other transport theo ries.
