The vibrational predissociation and electronic quenching dynamics of weakly bound OH-N z (A 2X +) complexes have been examined using laser-induced fluorescence and dispersed fluorescence. We find that predissociation occurs on a ~< 1 ps timescale for complexes prepared in levels correlating with OH

✦ Synopsis
The electronic spectra for the OH-H 2 and OH-D 2 complexes have been predicted from first principles. Our method relies on high quality ab initio calculations of a minimum energy path and an adiabatic separation of the bending vibrational modes. The model allows a simple interpretation and tentative assignment of an observed experimental spectrum of Loomis and Lester.
