In this thesis report, we describe a novel home-built instrument designed to study the spectroscopy of biomolecular ions in the gas phase and at low temperature, and we present the first experimental results obtained on protonated aromatic amino acids. The ...
On-line electrogeneration of mass tags in a microspray emitter is used to quantify the number of cysteine groups in a given peptide. A finite-element simulation of the multi-step process yields the relative distribution and concentration of tags, untagged ...
The absorption spectra of small silver and gold clusters are presented. The experimental technique consists in depositing clusters in an argon matrix which is illuminated with white light. By collecting the outcoming light from the matrix and by analysing ...
