A group of lines accompanying the first line of the Pfund series of the H atom has been observed by Fourier transform infrared spectrometry. The lines are due to transitions in molecular hydrogen of a nonpenetrating Rydberg electron possessing a high-orbital angular momentum, which is coupled only loosely to the vibrations and rotations of the H{sup +}{sub 2} core. Lines belonging to the 6{ital h}--5{ital g} and 6{ital g}--5{ital f} ({ital v}=0--3) transitions of H{sub 2} have been identified. The identifications are based on a calculation of the spectrum from first principles by multichannel quantum defect theory. The interaction between the nonpenetrating electron and the core was evaluated in terms of the permanent and induced molecular moments of H{sup +}{sub 2} as calculated by Bishop and collaborators. The analogous transitions in D{sub 2} have also been observed and assigned.
