The effect of the environment on doubly charged metallic subunits has been investigated in the gas phase through a combined experimental and theoretical study. The hybrid system consisting of an Ag 4 2+ cluster and a tryptophan molecule exhibits an unambiguous optical fingerprint, which can be useful to gain mechanistic insights into the aggregation and growth of nanoparticles (see figure; blue N, gray Ag, green C, red O, turquoise H).
