While a blue shift in the absorption spectra of particles with decreasing particle size is a sign of a delocalised excited state restricted in size by the volume of the particles, it is not a sign that this state necessarily only involves the inorganic core of the particles and is bulk-like. (5/N)

We also find that for most particles the optical gap is predicted to increase with decreasing particle size, even if the optical gap involves also the ligands. (4/N)

Only for nanoparticles with alkyl phosphines, phosphine oxides or amines as corner-capping ligands do we predict that the optical gap corresponds to an excitation that is primarily delocalised over the core with minimal contribution of the ligands, a true core-to-core bulk-like excitation. (3/N)
