The Au(144)(SR)(60) nanocluster has been a subject of structural conjecture since its initial description over a decade ago as a 29 kDa compound, yet a decisive empirical structure is elusive. Herein we show that (1)H NMR spectroscopy can provide a detailed view of ligand-layer equivalence for thiolate protected gold nanoclusters. We show that Au(25)(SR)(18), Au(38)(SR)(24) and Au(102)(SR)(44) nanoclusters have (1)H NMR spectra where the number of distinct chemical environments for the R-groups… CONTINUE READING
