Abstract
The effects of coupling between two adjacent electronic resonance states have been observed in several experiments involving dissociative attachment (DA) of electrons to diatomic molecules. When the potential energy curve of one resonance is attractive (possessing vibrational levels) and that of the other is repulsive, the coupling between the resonances may lead to the appearance of “vibrational” structure superimposed on a broad peak in the DA cross section. Such structure has been seen experimentally in (Inline), НCl3,4, HBr3,5, HF6, CO7, NO8 and some other molecules. When the potential energy curves of both resonances are repulsive, the effects of the coupling are less obvious. Nevertheless, such effects have been observed recently in experiments involving the formation of H– by electron attachment to HBr5.
