Estimation of Rate Constants for Gas-Phase Reactions of Chrysene, Benz[<i>a</i>]anthracene, and Benzanthrone with OH and NO₃ Radicals via a Relative Rate Method in CCl₄ Liquid Phase-System

CCl4 liquid-phase reaction kinetics of polycyclic aromatic compounds (PACs), including chrysene (CHRY), benz[a]anthracene (BaA), and benzanthrone (BA), with NO3 radicals were in...

Polycyclic Aromatic Hydrocarbons

Carbonaceous materials play an important role in space. Polycyclic Aromatic Hydrocarbons (PAHs) are a ubiquitous component of the carbonaceous materials. PAHs are the best-known...
