Prediction of rate constants for the gas phase reactions of triphenylene with OH and NO3 radicals using a relative rate method in CCl4 liquid phase-system

► Kinetics of CCl4 liquid-phase reactions of PAHs with NO3 radicals was investigated. ► Reaction rate constants of triphenylene with OH and NO3 radicals were determined. ► Relative loss rate of the atmospheric nitrotriphenylene was successfully evaluated.
