[HTML][HTML] Slow photoelectron velocity-map imaging of cold C7− and C9−
High-resolution anion photoelectron spectra of cryogenically cooled C 7− and C 9− clusters
obtained using slow photoelectron velocity-map imaging are presented, providing insight
into the vibronic structure of neutral C 7 and C 9. These spectra yield accurate
measurements of vibrational frequencies for the neutral clusters as well as electron affinities
of 3.3517 (4) and 3.6766 (14) eV for C 7 and C 9, respectively. In the C 7− spectrum,
transitions involving the previously unreported v 1 and v 2 symmetric stretching modes, as …
