✦ Synopsis

The infrared photodissociation of mass selected cluster-adsorbate complexes Au~-(CH3OH) m (m = 1-3) is studied in a Penning ion trap. Spectra are obtained by the excitation of vibrational modes of methanol, the desorption of neutral molecules and the detection of fragment ions by time-of-flight mass spectrometry. The photodissociation spectra are red-shifted with respect to the absorption frequency of free methanol. The number of photons necessary for the desorption of the adsorbate molecules and the respective separation energies are estimated.
