103Rh solid-state nuclear magnetic resonance (SSNMR) spectroscopy is potentially a powerful method for investigating the molecular and electronic structure of rhodium compounds. However, difficult nucleus to study by NMR because its small gyromagnetic ratio, broad chemical shift range, long spin-lattice relaxation times (T1). While there are many prior reports demonstrating acquisition solution spectra, few examples SSNMR spectra in literature. Here, we utilize large 31P-103Rh scalar couplings (J-couplings) efficiently acquire 31P-detected high-resolution spectra. 31P{103Rh} J-resolved experiments were used measure J-couplings. Sideband selective techniques originally developed wide-line 195Pt then rapidly Notably, able MAS experiment on order 30 min hours from only mg materials. The sideband offer significant time savings as compared existing direct detection methods, which require days obtain directly detected spectrum, or yield low-resolution static powder patterns. Numerical fits provide tensor parameters, with experimental agreeing well DFT-calculated
