Abstract:
Recently developed polarisation transfer techniques are applied to the nuclear magnetic resonance (NMR) of the coordination complex in solution. Four-bond - couplings of around 0.39 are exploited to enhance the NMR signal and to estimate the and relaxation times as a function of field and temperature. The longitudinal relaxation in is shown to be dominated by the spin-rotation mechanism, with an additional field-dependent contribution from the chemical shift anisotropy.
