CH2ClCN and CH2FCN show resonances near 3 and 8 eV, similar to those previously observed in CH3CN. In addition, both compounds capture electrons within a narrow resonance at very low energy (< 1 eV). While in CH2ClCN this low-energy negative-ion state is exclusively associated with Cl− formation, in CH2FCN a variety of fragment ions (F−, CN−, CHCN−, CHFCN−, CFCN−) are observed.
