✦ Synopsis
Electron attachment spectroscopy is employed to study negative ion formation from cyanogen. CN-is generated from a resonance at 2.7 eV with thermal kinetic energy, while a broad resonance centered at 5.5 eV yields CN-ions with considerable excess kinetic energy ( = 0.5 eV). The results are discussed in terms of a simple MO picture.
