We have studied the VUV photodissociation of gas-phase protonated leucine-enkephalin peptide ion in the 5.7 to 14 eV photon energy range by coupling a linear quadrupole ion trap with a synchrotron radiation source. We report VUV activation tandem mass spectra at 6.7, 8.4 and 12.8 eV photon energies and photodissociation yields for a number of selected fragments. The obtained results provide insights into both near VUV radiation damage and electronic properties of a model peptide. We could distinguish several absorption bands and assign them to particular electronic transitions, according to previous theoretical studies. Furthermore, the photodissociation yields appear to be very different for the various observed fragmentation channels, depending both on the type of fragments and their position along the peptide backbone. The present results are discussed in light of recent gas-phase spectroscopic data on peptides.
