Dissociation rates have been measured by multiphoton ionization and time-resolved photodissociation for benzene-d(6)(.+), naphthalene-h(8)(.+), naphthalene-d(8)(.+), and azulene-h(8)(.+) employing a quadrupole ion trap/reflectron mass spectrometer. Results compare favorably with available data from ICR cells and cylindrical ion traps. Azulene(.+) is photodissociated upon absorption of two 400 nm photons giving C2H2, H-., and H-2 eliminations. Dissociation rate constants measured for naphthalene(.+) and azulene(.+) at identical absolute energies are equal within experimental error. This experimental result is in agreement with previous density functional theory (DFT) calculations that demonstrated the isomerization of azulene(.+) to naphthalene(.+) below the dissociation limit of benzocyclobutadiene(.+) + acetylene.
