Table 1:

Aromatic VOC photooxidation conditions and particle data for NOx and H2O2 experiments, in which [H2O2]o and [NOx]o represent the initial hydrogen peroxide or oxides of nitrogen concentration introduced to the chamber, respectively, ΔHC is the change in hydrocarbon concentration upon oxidation, and yields are corrected for the wall losses.
