Short summary
The nuclear magnetic resonance (NMR) spectroscopy of the 103Rh nucleus is onerous owing to its dismal sensitivity. Here, we utilise modern techniques to boost the sensitivity and acquire valuable 103Rh NMR parameters for the Rh(acac)3 transition-metal complex. We acquire proton-enhanced 103Rh NMR spectra and successfully characterise the 103Rh spin relaxation. In doing so, we unveil the secrets of a complex that is of significant interest to the 103Rh NMR and wider chemical community alike.
