Reactions of Metastable and Ground State C Atoms

Chemiluminescence from CaX species (X = halogen) arises from the reaction of copper with Xj molecules. For Cu + Fj, ground-state copper atoms ( 5) react to produce A, B, and C states of CuF, with an inversion of population of the C state relative to the B state observed, whereas metastable Cu atoms ( D) are responsible for chemiluminescent reactions with the other halogens. Emission from GaF and InF ( 11) is seen in reactions of the ground-state Group Ilia atoms with F2, with population inversions formed in the vibrational levels of these excited states the products of ground-state reactions of and... 

The full collision of metastable Xe(6s, 3P2) atoms with BrCCl3 favors the formation of XeBr(B, C) rather than XeCl by a ratio of 2 1 (Setser and Qim 1991). This behavior is expected since in the ground state of BrCCl3 the electron is more likely to be located on the C Br antibonding orbital. In this process, the reaction starts on the covalent Xe -RX potential and evolves to the Xe+ RX potential, thus leading to XeX(B, C) products.
