Intensities of electric dipole forbidden rotation and rotation-vibration transitions in D2+

A full account of calculations of the electric dipole forbidden pure rotation and rotation-vibration transitions in the ground electronic state (1sσg) of D2+ is presented. The transitions have measurable intensity because of ortho-para mixing that arises from electronic g/u symmetry breaking caused by the Fermi contact hyperfine interaction. The transition moments for the most significant of these transitions (in the region 0.3...1000 cm-1) are determined to be between 5 710-3 and 7 710-6 ea0. \ua9 2004 Elsevier B.V. All rights reserved
