K. Fukui et al., Electron spin-echo envelope modulation spectral properties of amidate nitrogen coordinated to oxovanadium(IV) ion, CHEM LETT, (3), 2000, pp. 198-199
Electron spin-echo envelope modulation (ESEEM) measurements have been perfo
rmed for a VO2+-amidate complex, [(VO)-O-IV(hybeb)](2-) (H(4)hybeb = 1,2-bi
s(2-hydroxybenzamido)benzene). ESEEM spectroscopic properties of the amidat
e N-14 nucleus have been characterized for the first time (\ A(iso)\ = 6.70
MHz; e(2)qQ/h = 2.5 MHz, eta = 0.04) to provide a basis for the studies of
vanadium-peptide interactions. The electronic structure of the amidate nit
rogen is discussed.
