Abstract
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.
