Abstract

The rationally resolved infrared spectrum of the Br--D2 anion complex was measured in the D2 stretch region by monitoring the production of Br- photofragments in a tandem mass spectrometer. The effective radial potential at longer separations was derived from the long range electrostatic and induction potential energy. The rotationally resolved spectrum consists of two overlapping σ-σ subbands, red-shifted by approximately 85 cm-1 from the free D2 vibrational frequency. The subbands assigned to absorptions by Br--D2 complexes were analyzed with respect to para and ortho forms of the D2 molecule.
