摘要：

(Figure Presented) From radical to biradical: The pulsed-field-ionization zero-kinetic-energy photoelectron spectrum of the C5H5 radical is recorded after direct excitation from the X̃ 2E″1 ground state and two-photon excitation via the Ã 2A″2 electronically excited state. The intensity distributions of the spectra enables the characterization of the energetics, symmetry, and structure of the lowest two electronic states of the cation (see picture). © 2006 Wiley-VCH Verlag GmbH & Co.
