Ring-Selective Fragmentation in the Tirapazamine Molecule upon Low-Energy Electron Attachment

Ring-Selective Fragmentation in the Tirapazamine Molecule upon Low-Energy Electron Attachment

We investigate dissociative electron attachment to tirapazamine through a crossed electron–molecule beam experiment and quantum chemical calculations. After the electron is attached and the resulting anion reaches the first excited state, D<sub>1</sub>, we suggest a fast transition into...
