Visible Multiphoton Dissociation of Chromophore-Tagged Peptides |pdf=|usr=}}{{28755260}} gab.com Text Visible Multiphoton Dissociation of Chromophore-Tagged Peptides JO: J Am Soc Mass Spectrom http://www.kidney.de/pget.php?&tw=1&pmid=28755260 #FOAvip The visible photodissociation mechanisms of QSY7-tagged peptides of increasing size have been investigated by coupling a mass spectrometer and an optical parametric oscillator laser beam. The experiments herein consist of energy resolved collision- and laser-induced dissociation measurements on the chromophore-tagged peptides. The results show that fragmentation occurs by similar channels in both activation methods, but that the branching ratios are vastly different. Observation of a size-dependent minimum laser pulse energy required to induce fragmentation, and collisional cooling rates in time resolved experiments show that laser-induced dissociation occurs through the absorption of multiple photons by the chromophore and the subsequent heating through vibrational energy redistribution. The differences in branching ratio between collision- and laser-induced dissociation can then be understood by the highly anisotropic energy distribution following absorption of a photon.Graphical Abstract?Electronic supplementary material: The online version of this article (doi:10.1007/s13361-017-1733-9) contains supplementary material, which is available to authorized users.
