Fragmentation of Protonated Polycyclic Aromatic Hydrocarbon (PAH) Cations

摘要

Coronene can yield fragment upon IRMPD. Coronene cation is photodissociated greatly at the wavelengths of 9.210 (mu)m, 9.329 (mu)m and 9.552 (mu)m. No fragment loss is observed when the wavelength is greater than 10.136 (mu)m. Pyrene cation losses H_(2) without CO_(2) laser radiation. After photodissociation, It yields fragment.
