Coherent multidimensional spectroscopy of molecules embedded in different environments
Coherent multidimensional spectroscopy enables insight into intra- and inter- molecular couplings on ultrashort time scales. We apply two-dimensional electronic coherence spectroscopy by acousto-optic phase modulation to molecular samples in the gas phase and attached to rare-gas clusters, providing cold temperatures and weak perturbation of an environment. With these techniques we aim at a better understanding of ultrafast processes in molecules (e.g. pentacene, tetracene, etc.) in a bottom-up manner, which could promote the study of photosynthesis, photovoltaic, and photocatalysis. On the experimental side, in particular an improved optical setup and the combination with photoelectron spectroscopy is in the focus of the project.
