This simple theoryis based on the expectation that, to a reasonable degree of approximation, proton-proton, dipolar contributions to the measured spin-lattice relaxation-rate are pairwise additive and decrease as a simple sixth power of the interproton distance. The simplified version of the dipole-dipole mechanism is summarized in the following two equations for spin i coupled intramolecularly with a group of spins j...

M(i) and Cu(i) complexes. For nickel, it has been generally observed that the lower the oxidation potential for the Ni(ii)/Ni(m) couple, the more negative is the reduction potential for the Ni(n)/Ni(i) couple.

Reduction potentials (Eg) for different plastocyanins, the PCu(II)/PCu(I) couple, have been determined by spectrophotometric titration against, e.g. [Fe(CN)e] . At pH 7.5 for higher plant and green algal plastocyanins values are close to 370 mV at 25 °C, 1=0.10 M(NaCl) [1]. Thus French bean gives a value 360 mV and S. obliquus 363 mV [50]. However, A. variabilis gives an... 

However, in the reaction of vitamin BjjS with primary halides and with benzyl chloride, where the 8 2 driving force can be calculated from the standard potential of the Co(ii)/Co(i) couple and from existing Co—C bond energy data, it appears that recasting the kinetic data point against DF Sf 2) instead of DF ET) brings it close to the ET line (Walder, 1989).

Relativistic Quantum Defect Orbital (RQDO) calculations, with and without explicit account for core-valence correlation, have been performed on several electronic transitions in halogen atoms, for which transition probability data are particularly scarce. For the atomic species iodine, we supply the only available oscillator strengths at the moment. In our calculations of /-values we have followed either the LS or I coupling schemes.
