Combined IR/UV spectroscopy in the gas phase: From isolated peptides to proton wires and metal/ligand aggregates
Hydrogen bonds range among several biological and photoreactive systems. The application of mass and isomer selective combined IR/UV spectroscopy to isolated molecules and clusters in molecular beam experiments offer very powerful techniques to investigate e.g. driving forces to form secondary structures in peptides, processes of microsolvation, reactions in electronically excited states or catalytical activations in metal containing aggregates.
An overview ranging from the analysis of peptide aggregates to transition metal/aclohol clusters up to a detailed IR analysis of proton wires in electronically excited states of flavonoids is given.
