A complete ab initio optimization of the nitroxides (I and II) was performed at the UHF-SCF level, using a 6-311G** basis set, followed by a gradient optimization of the NO bond at the MP2 level. Exptl. structural and spectroscopic findings are well reproduced by the calcns. A precise attribution of the couplings of the two inequivalent nitrogens in the iminonitroxide has been achieved, underlining the need for highly correlated wave functions in order to obtain accurate results
