Good vibrations : Metal–molecule–metal nanosystems are fabricated by the self‐assembly of gold and silver nanoparticles interconnected with 4‐aminothiophenol (PATP) molecules (see picture). The b 2 vibrational modes of the PATP molecules are greatly enhanced by near‐infrared excitation, as a result of charge transfer between the metal nanoparticles coupled with the vibrations of the PATP molecules.
