Electron-Transfer-Induced Side-Chain Cleavage in Tryptophan Facilitated through Potassium-Induced Transition-State Stabilization in the Gas Phase

da Silva, Filipe Ferreira; Cunha, Tiago; Rebelo, Andre; Gil, Adrià; Calhorda, Maria José; García, Gustavo; Ingólfsson, Oddur; Limão-Vieira, Paulo (American Chemical Society (ACS), 2021-03-25)

Fragmentation of transient negative ions of tryptophan molecules formed through electron transfer in collisions with potassium atoms is presented for the first time in the laboratory collision energy range of 20 up to 100 eV. In the unimolecular ...
Proton Shuttling and Reaction Paths in Dissociative Electron Attachment to o- and p-Tetrafluorohydroquinone, an Experimental and Theoretical Study

Ómarsson, Benedikt; Bjornsson, Ragnar; Ingólfsson, Oddur (American Chemical Society (ACS), 2017-07-21)

Here we present a combined experimental and theoretical study on the fragmentation of o- and p-tetrafluorohydroquinone upon low energy electron attachment. Despite an identical ring-skeleton and identical functional groups in these constitutional ...
