The interaction of molecules with plasmonic nanoparticles is at the core of
empirically well-established optical and spectroscopy-relevant phenomena such
as surface-enhanced Raman scattering or surface-enhanced fluorescence. The
excitation of localized surface plasmons is in fact able to provide various
orders of magnitude amplification of the molecular optical signals, allowing
single molecule investigations. More recently, such interaction is being
exploited in ultrafast time-resolved spectroscopy, to provide access to the
real time behavior combined with the high sensitivity provided by
plasmon-enhancement [1,2]. In this contribution, I will describe our
methodological efforts to simulate time-resolved spectroscopy of molecules
close to plasmonic nanoparticles, based on a hybrid description of the molecule
(QM) and metal (classical) system and the use of equations of motion to
represent the electromagnetic metal response [3]. This project has received
funding from the European Research Council (ERC) under the European Union’s
Horizon 2020 research and innovation programme under grant agreement No 681285.
