Abstract

Bond formation in 1,8-dimethylenenaphthalene neutrals and cations (C₁₂H₁₀^(+•), 154 amu) was probed with mass spectrometry, pyrolysis/photoelectron photoion coincidence spectroscopy (py-PEPICO) and theory. The mass-analyzed ion kinetic energy (MIKE) spectra and neutralization–reionization (NR) mass spectra obtained for m/z 154 from directly ionized acenaphthene (1) and dissociatively ionized 1,8-bis(bromomethyl) naphthalene (C₁₂H₁₀Br₂, 1,8-BM) were distinguishable. Combined with theory, the results were interpreted as the two sources forming 1^+• ions with different average internal energy contents. Pyrolytic debromination of 1,8-BM was found to produce both acenaphthene 1 and acenaphthylene.

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
