Abstract	The formation of isolated [ (Trp-2H)+Ag9] + and [ (Tyr-2H)+Ag9] + amino-acid-Ag9 hybrids is reported. The photofragmentation yields of the aromatic amino acid-silver cluster hybrids, as well as those of the protonated tryptophan and tyrosine molecules ([Trp+H]+ and [Tyr+H]+) have been recorded. The fragmentation yields of the complexes are higher than the yields for [Trp+H]+and [Tyr+H]+ and present an extension of the fragmentation on the red side of the spectrum. The photofragmentation spectrum of [ Trp+Ag9] + was recently reported [Mitric et al., J. Chem. Phys. 127, 134301 (2007)]. While the optical spectra of substituted [ (Trp-2H)+Ag9] + and non-substituted [ Trp+Ag9] + complexes are very similar, a strong modification of the fragmentation channels between the two complexes is observed. The fragmentation channels are sensitive to the type of bonding in aromatic amino acid-silver cluster hybrids and can be used as fingerprints of structures.
