Abstract

The infrared photodissociation spectra of Aun(C2H5OH)m (n = 3, 9, 11; m = 1-4) complexes have been recorded in the 9-11 μm region. The ethanol vibrational band frequencies are observed to be invariant with the size of the underlying gold clusters, indicating that local, rather than global, interactions determine the frequency shifts from the gas-phase values. Experimental results are compared with electronic structure calculations for both Au3(C2H5OH) and Au3(CH3OH). From these calculations a model for the binding of the single alcohol to the gold cluster is proposed which qualitatively accounts for many of the experimental observations.
