Abstract We report the results of {sup 31}P NMR measurements on trioctylphosphine oxide (TOPO) passivated InP quantum dots. The spectra show distinct surface-capping sites, implying a manifold of crystal{endash}ligand bonding configurations. Two In {sup 31}P surface components are resolved and related to different electronic surroundings. With decreasing particle size the In {sup 31}P core resonance reveals an increasing upfield chemical shift related to the overall size dependence of the InP electronic structure. {copyright} {ital 1999 American Institute of Physics.}
