The infrared spectrum of the linear OD-N-2 complex has been recorded in the OD overtone region near 1.9 mum using an infrared-ultraviolet double resonance technique. The pure overtone band of OD-N-2(2 nu (OD)) was observed at 5173.99(1) cm-1, and combination bands involving the simultaneous excitation of OD stretch and geared bend were identified at 5209.02(1) cm-1 and 5214.59(2) cm-1. Assignments and spectroscopic constants have been derived from the rotationally resolved structure of each band, which are in good accord with model calculations based on an electrostatic interaction potential. Direct time-domain measurements yielded a vibrational predissociation lifetime of 150 +/- 16 ns for OD-N-2 (2 nu (OD)) and a three fold decrease in lifetime upon intermolecular excitation of the lower-energy geared bending state. The OD (v=1) fragments of vibrational predissociation were found to be highly rotationally excited, indicating that predissociation proceeds by vibrational to rotational/translational energy transfer. The results obtained for OD-N-2 are compared with an analogous study of OH-N-2 [Marshall , J. Chem. Phys. 114, 7001 (2001)], revealing insights on the potential anisotropy along the geared bending coordinate and a change in the vibrational predissociation mechanism.
