Notes:
The A 2Δu←X 2Πg, B 2Σu−←X 2Πg, and C 2Σu+←X 2Πg electronic transitions of C3− were observed in a neon matrix and in the gas phase, although the energy of the excited electronic states involved in these transitions is 1–1.5 eV above the photodetachment threshold. The excited Feshbach states are sufficiently long-lived that some of the bands in the gas-phase photodetachment spectrum exhibit rotational structure. Assignment of the transitions is made on the basis of rotational analysis or profile simulations and theoretical calculations. The b 4Πu←X 2Πg transition is also weakly observed. The presence of such discrete bands, though in the continuum, provides a means of detection for anions in the interstellar medium. © 2000 American Institute of Physics.
