Abstract
Various spectroscopic and photochemical properties of the acenaphthylene radical cation have been determined. Acenaphthylene cations were generated by low energy electron impact, deposited in solid argon at 12 K, and studied via Fourier transform infrared (FT-IR) and visible/UV absorption spectroscopy. In addition, the gas-phase IR spectrum of cationic acenaphthylene was obtained via multiphoton dissociation spectroscopy of the species stored in a quadrupole ion trap, using the intense and widely tunable radiation of a free electron laser. These two sets of results have been compared to the calculated (B3LYP/6-31G(d) and BP86/6-31G(d)) vibrational spectra of neutral and cationic acenaphthylene to aid in spectral band assignments. Large differences between the calculated IR intensity distributions of neutral and cationic acenaphthylene are predicted. The observed spectra are consistent with the predictions. The conversion of acenaphthylene (C12H8) into acenaphthene (C12H10) was observed upon deposition of ...
