Photoinduced Non-Equilibrium Dynamics in Molecular Adsorbates: From Ensemble to Single-Molecule Experiments

Schlücker

The influence of the local environment on the photoinduced non-equilibrium dynamics of molecules, specifically the intramolecular proton transfer in 2-(2‘, 4‘-dinitrobenzyl)pyridine (-DNBP), is investigated. For label- and contact-free monitoring of this process, we employ femtosecond time-resolved surface-enhanced nonlinear vibrational Raman scattering in combination with plasmonically highly active nanoantenna dimers and develop this method further towards single-molecule detection.
