| Abstract: | Broadening of the 195Pt satellites in the 1H NMR spectrum of trans-Pt(ethene)(2-carboxy-pyridine)Cl2 at high field arises from relaxation of 195Pt via the chemical shift anisotropy mechanism. We also demonstrate that well-resolved 14N-195Pt couplings can be observed in 195Pt NMR spectra of Pt(II) and Pt(IV) amine complexes, including anti-tumour agents, at elevated temperature where scalar coupling contributions to 195Pt relaxation are much reduced. |
