Decomposition of propionyl chloride triggered by slow electrons
Low energy electron attachment to propionyl chloride is studied by means of a crossed beam experiment. Two distinct resonances are observed located near 0 and 0.7 eV. The first resonance is attributed to a temporary occupation of the lowest unoccupied molecular orbital (LUMO) with predominant pi(C = o)*, character. It mainly decays into Cl-, but also the fragments (M-CH2)(-), COCl- and (M-Cl)(-) are observed. In addition the non-decomposed parent molecular anion M- is observed. The second resonance exclusively leads to Cl- formation. It is characterized as temporary occupation of a repulsive sigma(C-Cl)* MO.
