Abstract

Experimental gas phase infrared spectra are presented for four cationic polyaromatic hydrocarbons (PAHs) incorporating a Five-membered ring, indane, acenaphthene, fluorene, and fluoranthene. The ions are stored in a quadrupole ion trap and irradiated with the intense narrow-band infrared light of afree electron laser (FEL). When the wavelength is in resonance with an allowed infrared transition in the ion, multiphoton absorption occurs, resulting in dissociation. Recording the fragment ion yield as a function of FEL wavelength gives a background-free infrared spectrum of the parent ion species. Experimental spectra are found to be in good overall agreement with density functional calculations, except for those for the fluoranthene cation.
