摘要：
The laser-induced fluorescence (LIF) excitation spectrum of gas-phase hexafluorobenzene cations (C6F6+) has been measured at room temperature, by ion trapping and cyclotron frequency-based mass-selection. The optical spectral resolution, vibrational state assignments, and their corresponding wavelengths compare favorably to prior data [J. Chem. Phys. 70 (1979) 138]. The present approach offers a general entry into optical spectroscopy of collisionally stable gas-phase ions. (C) 2001 Elsevier Science B.V. All rights reserved.
