Description
Plasmon is a collective electronic excitation that occurs in irradiated metallic nanoparticles (NPs) [1]. Plasmonic excitation is intense and sharp, and can be exploited to modify, even qualitatively, the properties of molecules interacting with an NP. In this presentation, the key ideas of molecular plasmonics [2], i.e., the study of the photoinduced interaction between molecule and NP, are given. A theoretical multiscale time-domain approach [3] was applied to study the selectivity toward methane in the photocatalytic hydrogenation of carbon dioxide in the presence of a rhodium nanocube [4,5], and to verify the plasmon enhancement of the circular dichroism signal in chiral molecules [6].
