✦ Synopsis
Electronic chemiluminescence
from the reaction of selected ground state (2SI,2) or metastable ('D,,,, 2D1,,) copper atoms with fluorme has been studied using a hollow cathode-flowing afterglow reactor. The observed signal related to the Cu (%S) and Cu* ('D) atom densities, indicate that the chemiluminescence cross-section for Cu* ('D) atoms is about lo4 times larger than for Cu ('S) atoms. This strong propensity is explained in terms of a direct reaction, initiated by a harpooning process, during which the Cu+ ion core of the reactant (3d"' for Cu(%) and 3d94s for Cu*(*D))
is conserved in the products (ionic structure Cut (3d")F-for the CuFground state and Cu+ (3d'4s)F-for the CuF*(a, A, B, C, D) chemihtminescent states).
