The efficiencies of energy transfer from electronically excited thallium, Tl(6p 2P3/2), to a variety of collision partners have been measured and compared to similar processes involving iodine, I(5p5 2P1/2). Several mechanisms are discussed, and the possible role of ionic charge transfer complexes in facilitating such energy transfers assessed. Such complexes appear to play a significant role in the deactivation of Tl(6p 2P3/2) by molecules with positive electron affinities. The production of electronically excited thallium by energy transfer from O2(1Δg) is discussed, this latter species being formed chemically in the reaction of electronically excited oxygen atoms, O(2p4 1D2), with N2O.
