Atomic cluster Au10+ is a strong broadband mid infrared chromophore

Abstract:

We report an intense broadband mid infrared absorption band in the Au10 + cluster in a region in which only molecular vibrations would normally be expected. Observed in the infrared multiple photon dissociation spectra of Au10Ar+ , Au10(N2O) + and Au10(OCS) + , the smooth feature stretches 700–3400 cm-1 (=14–2.9 µm). Calculations confirm unusually low-energy allowed electronic excitations consistent with the observed spectra. In Au10(OCS)+ , IR absorption throughout the band drives OCS decom...
