We report on an experimental single-photon absorption study on gas-phase protonated collagen peptides employing a combination of mass spectrometry and synchrotron radiation. Partial ion yields for the main photoabsorption products vary steadily with

International audience; UV photodissociation of proline-containing peptide ions leads to unusual product ions. In this paper, we report laser-induced dissociation of a series of proline-containing peptides at 213 nm. We observe specific fragmentation

We have studied the dissociation of the gas-phase protonated peptide leucine enkephalin [YGGFL+H](+) upon X-ray absorption in the region of the C K-edge. The yield of photodissociation products was recorded as a function of photon energy. The total p
