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)₃transition-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.
