Resonance-enhanced multiphoton electron detachment spectra of C7−, C9−, and C11−

Abstract

Electronic spectra of C7−, C9−, and C11− were measured in the gas phase for the first time using resonance-enhanced detachment. The band origin of the transition to the lowest excited state for each of these three anions was determined. For C7− and C9−, several other higher excited states were also detected. The 000 transitions for a series of linear chain anions from C5− to C11− were compared with those previously reported for even-numbered series. Slight differences were noted between the even- and odd-numbered series.
