Triatomic dissociative recombination theory: Jahn–Teller coupling among infinitely many Born–Oppenheimer surfaces
Abstract
The coupling of many Rydberg surfaces poses a stringent challenge for theoretical description. Yet simplifications arise because quantum defect ideas can be applied, which circumvents some of the usual difficulties that arise. We describe a theoretical technique capable of handling these complex interactions, which has already been applied with success to the dynamics of H3 Rydberg states. The extensions necessary to treat the other isotopomers H2D+ and HD2+ are then discussed, along with a preliminary application.
