New light on the imbroglio surrounding the C₈H⁺₆ isomers formed from ionized azulene and naphthalene using ion-molecule reactions.

ABSTRACT: Most polycyclic aromatic hydrocarbons (PAHs) can isomerize with internal energies near to or below the dissociation threshold. The C₁₀H⁺₈ group of ions, made up of the naphthalene (Naph⁺) and the azulene (Azu⁺) radical cations, is a prototypical example. C₈H⁺₆ isomers are important species in the growth kinetics and formation of complex organic molecules, and more generally fragments from larger PAHs, yet information about C₈H⁺₆ structures is scarce and contradictory. Here, ion-molecule reactions were carried out and the tunable photoionization chemical monitoring technique was used to probe the C₈H⁺₆ isomers formed upon C₂H
