Electron spin echo envelope modulation (ESEEM) spectroscopy has been applied to several nitrogen-coordinated oxovanadium(IV) complexes. Results for two amine-nitrogen complexes, VO(edda) and VO(gly)(2), two imine-nitrogen complexes, VO(salen) and VO(salophen), and one isothiocyanate complex, VO(NCS)(4)(2-), are presented, [H(2)edda = ethylenediamine-N,N'-diacetic acid, gly(-) = lycinate, H(2)salen = N,N'-bis(salicylidene)ethylenediamine, and H(2)salophen = N,N'-bis(salicylidene)-o-phenylenediamine.] The N-14 hyperfine coupling (HFC) and quadrupole coupling (NQC) parameters have been determined from computer simulation of the two-pulse and three-pulse ESEEM data recorded at some selected field positions. Resulting NQC parameters are e(2)qQ = 3.1 MHz (VO-(edda)), 2.7 MHz (VO(gly)(2)), 2.4 MHz (VO(salen)), 2.6 MHz (VO(salophen), and 1.0 MHz (VO(NCS)(4)(2-)). The isotropic HFC parameters, [A(iso)], show a good correlation to the nitrogen type as 4.98 MHz (VO(edda)), 5.10 MHz (VO(gly)(2)), 5.83 MHz (VO(salen)), 5.78 MHz (VO(salophen)), and 7.47 MHz (VO(NCS)(4)(2-)). The isotropic and anisotropic parts of the HFC parameters are analyzed in terms of the indirect spin transfer mechanism. The analysis has given good quantitative agreements, supporting the validity of this mechanism. According to the mechanism, the isotropic pair of HFC depends essentially on two factors, the degree of the (negative) polarization of the nitrogen lone-pair sp(n)-hybrid orbital and the s orbital content of this orbital. The analysis has shown that the polarization is invariably around -1%. Thus, the good correlation can be attributed to the distinct difference of the s-orbital contents between nitrogen types.
