title: Observation of uniform ligand environments and (31)P-(197)Au coupling in phosphine-terminated Au nanoparticles.
abstract: Here, we use solution and solid-state (31)P NMR to study the ligand environment of water soluble, phosphine-terminated gold nanoparticles. The resulting spectra indicate that particle-bound phosphine ligands occupy an unexpectedly monodisperse ligand environment. This uniformity then facilitates one of the first descriptions of distinct (31)P-(197)Au coupling in colloidal nanoparticles.
