WebFeb 2, 2024 · The reactive radicals react with these three probe compounds via radical-addition and H-abstraction pathways. The DFT-calculated first-order rate constants ( k CP C ) can be explained by the sum of initial reaction rate constants for • OH, • ClO, and • Cl reactions with each probe compound. WebSimulations examine the effects of 1) previously-unmeasured reactive VOC identified in recent laboratory studies, and 2) emissions and secondary production of nitrous acid (HONO). Inclusion of estimated unmeasured VOC leads to a 250% increase in OH reactivity and a 70% increase in radical production via oxygenated VOC photolysis. impact brooklyn website
