Notes:
We report the first measurement of a polycyclic aromatic hydrocarbon cation electronic transition in the ultraviolet spectral region. The UV excitation spectrum of the Dn–XD0 transition of the perylene cation (C20H12+) isolated in an argon matrix was pumped with tunable, coherent radiation and monitored using the vibronic bands of the D1(2B3g)→(2Au)D0 system. The two component band peaks at 244 and 250.2 nm, close to the S2(1B3u)←(1Ag)S0 transition in neutral perylene. © 1999 American Institute of Physics.
