title: Photochemical control of molecular motion associated with pyramidal inversion.
abstract: Rates of pyramidal motion in an aziridine are controlled by reversible trans to cis photoisomerisation of an azobenzene unit attached to the ring nitrogen atom. The dynamics of the inversion process and activation parameters are derived by variable temperature NMR, and are supported by ab initio calculations.
