Notes:
Multistate perturbation theory has been used to assign high resolution Rydberg spectra of H2 and D2 in the infrared. The theoretical model treats interactions between the H+2 ion core and the spatially extended case (d) Rydberg electron in terms of the multipole moments and polarizabilities of H+2. The long range interaction model of Sturrus, Hessels, Arcuni, and Lundeen [Phys. Rev. A 38, 135 (1988)] was refined to include terms up to r−8 in the Rydberg electron radial matrix element. Implementation of the multipole moment–polarization matrix diagonalization model was carried out at three levels: Rotation only ("pure precession''), vibrationally extended, and full multichannel. At each level the calculations were made to order r−4 (low order), r−6 ( (1)/(2) V6) and r−8 (high order). The most generally successful model was found to be the (1)/(2) V6 vibrationally extended model.
