Vibrationally Resolved Spectra of C2-C11 by Anion Photoelectron Spectroscopy

Abstract

Anion photoelectron spectroscopy has been employed to obtain vibrationally resolved spectra of the carbon molecules C2 through C11. The spectra of C2(-) through C9(-) are dominated by linear anion to linear neutral photodetachment transitions. Linear to linear transitions contribute to the C11(-) spectrum, as well. From these spectra, vibrational frequencies and electron affinities are determined for the linear isomers of C2-C9 and C11. Term values are also obtained for the first excited electronic states of linear C4 and C6. The spectra of C10(-) and C11(-) show evidence for transitions involving cyclic anions and/or neutrals. Similars types of transitions are identified in the spectra of other smaller molecules, specifically C6(-), C8(-), and to a lesser extent C5(-).
