Structural and optical properties of the Ag_n-tyrosine complexes (n = 3-12): a density functional theory study.

ABSTRACT: We study the optical properties of Ag_n (n = 3-12) neutral clusters and their coordination with a tyrosine (Tyr) molecule. A global search strategy coupled with density functional theory (DFT) computations explored the potential energy surface. Adsorption energy calculations predicted that Tyr coordination stabilizes the metal clusters, favouring the Ag_n-Tyr complexes with an even number of silver atoms. For the Ag_n low-lying isomers, the general shape and the major transitions of the calculated time dependent-DFT (TD-DFT) absorption spectra align with those of previous reports measured in an argon environment. We use the analysis of non-covalent interactions to identify the specific interactions between each silver cluster and fu
