- 3-butadiyne). The selectivity of vibrational excitation reveals detailed information about the shape resonances. Excitation of the C≡C stretch and of double quanta of the C-H bend vibrations reveals a ²Πu resonance at 1 eV (autodetachment width ~30 meV) and a ²Πg resonance at 6.2 eV (autodetachment width 1–2 eV). There is a strong preference for excitation of even quanta of the bending vibration. Excitation of the C-H stretch vibration reveals σ* resonances at 4.3 (1)

with autodetachment widths of ~2 eV. Detailed information about resonances permits conclusions about the mechanism of the dissociative electron attachment. (1)
