β¦ Synopsis
Tile r:ltc of production of NOB by energy transfer from tional to [02(l$J] singlet molecular oxygen is showr. to be propor-~YCII under conditione where [O~(~xa] IS not proportional to [02(lAa)]". This helps establish Z = k[O2('$)] [02( b )I INOB] 3s the rate law for the 0; + NO2 energy transfer process. Evidcncc for cncrgy transfer from N & 2 to O2 is reported. Excitation of NO2 by energy transfer from 05 was first reported by Bader and Ogryzlo [II. Arnold [2] has established that ZNO~ a [O,( lAg)j3 in a discharge flow system. This rate law is consistent with an overall reacti& of either 302&d + NO2 -NO; + 302

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
Ultraviolet emission produced by photoexcitation ofN0 at 50-80 nm is observed using synchmtmn radiation as a light source. The emission increases at an excitation wavelength corresponding to the ionization potential of the NO+ (a) state. The emission spectra at several excitation wavelengths are di
## Abstract The lowβpressure recombination rate constants of the reactions I + NO + M β INO + M (with 14 different M) and I + NO~2~ + M β INO~2~ + M (with 26 different M) have been measured at 330Β°K by laser flash photolysis. The collision efficiencies Ξ²~c~ are analyzed and compared with other ther
