Description
Electron capture by molecules leads to the formation of transient negative ions, which may dissociate through dissociative electron attachment (DEA). DEA to the 1-bromoacetyl-3,3-dinitroazetidin (RRx-001) molecule in the gas phase has been studied utilizing a crossed electron-molecular beam setup combined with a quadrupole mass spectrometer. RRx-001 has been proposed as a radiosensitizer. We observed 11 fragment anions, which indicate that low-energy electrons with kinetic energies ranging from 0 to 14 eV strongly decompose the molecule. The results indicate efficient formation of NO2– and Br– upon DEA to RRx-001.
