【 摘 要 】

We present an overview on the photoactivation of gaseous peptide ions and point out the importance of synchrotron-based activation of peptides and proteins. Particularly, we present results on the action spectroscopy of substance P peptide in vacuum-ultraviolet (VUV) and discuss the importance of VUV -induced neutral losses over a wide photon energy range.
