- Аннотация: This study is devoted to the estimation of dissociation rates for polycyclic aromatic hydrocarbons(PAHs) molecules due to ultraviolet photon absorption. Four methods are used for calculations. Specifically, the rates of dehydrogenation and destruction of the PAH carbon skeleton are calculated. The results obtained by different methods are compared. It is shown that the results differ significantly, and it is impossible unambiguously estimate minimum sizes and the degree of PAH hydrogenation. The results indicate the need to refine the theoretical models of PAH photodissociation and expand the experimental basis of PAH dissociative properties.
