Chemiluminescent Reactions of the Excited Noble-gas Atoms

Mechanisms of the Chemiluminescent Reactions of the Excited Noble-gas Atoms.— The close analogy between the potential curves of the excited noble gas halides and the ground-state alkali halides has been taken to imply analogies between reactions (54) and alkali atom reactions  

There is increasingly good evidence that this model is applicable to the reaction of the Rj states of Ar, Kr, and Xe with the halogen molecules, X2. The ionization potentials of these states are small (Table 1) and close to those of the alkali atoms. The total quenching cross-sections for their reactions with CI2 and Brj are very close to the reaction cross-sections of K, Rb, and Cs with these halogens. For Kr( R2) + Fj, the branching ratio for the formation of KrF is approximately unity and probably similar for Xe( R2) + F , CI2, and Brj (ref. 100). For 

The yields of ArO from the reactions of Ar( P ) with N2O, OO, and O3 are very low. - With the first two reagents, major channels include
