Chemical reactions leading photochemical smog

This paper presents some of the chemical measurements observed in our chambers in 200 experiments involving approximately 50 individual compounds, most of which are commercial solvent components. To correlate chemical reactivity with structure, we also review many of the observations and conclusions of other investigations into solvent reactivities. Although the chemical reactions leading to photochemical smog... 

Figure 4.1. Breakage of a chemical bond between N and O in NO2 starts the process involving a series of many reactions leading to the formation of unhealthy pollutant photochemical smog.
