Controlled ultrafast ππ*-πσ* dynamics in tryptophan-based peptides with tailored micro-environment

Pump-probe experiments in the gas phase usually target neutral molecules. Here the authors couple an electron spray source with ultrafast pump-probe UV-Vis spectroscopy, to follow the ππ*-πσ* coupling in tryptophan-based ions.
