Abstract

Low energy electron attachment to gas phase carbonyl fluoride, F2CO, has been performed by means of a crossed electron-molecular beam experiment in an electron energy range from 0 to 30eV with an energy resolution of ∼0.5eV. The most intense signal is observed at 19amu due to F− and two other anionic species with lower intensities at 38 and 47amu assigned to F2− and COF−, respectively. Anion efficiency curves of the three anions have been measured. Product anions (F− and COF−) are observed mainly in the low energy region arising from simple bond breaking, while F2− is being produced from two bond cleavages with further structural and electronic rearrangement. Quantum chemical calculations on the electronic properties of F2CO have been performed in order to complement the experimental results.
