Photoelectron Imaging Spectroscopy of AuC3H(-) Anions: Four Isomers.
Laser ablation generated AuC3H(-) anions were skimmed into a time-of-flight mass spectrometer (TOF-MS) and selected with a mass gate. Photoelectron spectra of AuC3H(-) were recorded using the velocity map imaging technique at several photon energies. The experimental spectra, quantum chemistry calculations, and Franck-Condon simulations suggest that the AuC3H(-) cluster has four structure isomers, including one unexpected structure of [C═C═C-Au-H](-). When AuC3H(-) is compared with C3H2(-), introduction of gold into the hydrocarbon system results in the much lower isomerization barriers.
