Abstract We present optical extinction spectra of ligand-stabilized Au-clusters AuN with sizes of N=13 and N=55. They are compared to larger, embedded clusters up to N=5·103 (diameter 5nm). The Mie resonance due to excitation of the dipole plasmon polariton vanishes with decreasing cluster size. For N〉55, this effect has recently been interpreted as caused by smearing out of the interband transition edge of Au.
