Study of the Resonance Structures of the Preionizing Spectrum of Molecular Hydrogen by Phase-Shifted Multichannel Quantum Defect Theory II

We obtain the general formulation which can handle the rotational preionization spectrum of H2 in the region above its H2 + ionization threshold, converging toward its rotationally excited limit and perturbed by the vibrationally excited levels 7pπ v = 1 and 5pπ v = 2. The formulation is based on phase-shifted multichannel quantum-defect theory. With this formulation, resonance structures are analyzed in detail
