โฆ Synopsis
Photoionization studies have shown that Oz(a' A) is form& by energy transfer from electrbnicdy excited NO2. The efficiency of this energy transfer process is sufficient to make it a.major source of sin&etinokular oxygen in polluted urban atmospheres. The photolysis of NO2 by ultraviolet radiation is NO,, and 02(al A), but not ground state Oi(XSZ). known [l] to proceed by the reactions
