## Abstract The thermodynamic products (Ξ΅βlactams) of the degradation of ten different spirocyclic oxaziridines were analyzed by ^1^H and ^13^C NMR spectroscopy. The preferred conformations were determined by examining the homonuclear spinβspin coupling constant and the chemical shift effects of th
