Abstract
Two-color, pump-probe spectroscopy has been used to investigate the vibrational predissociation dynamics of numerous conformers of hydrogen-dihalogen complexes. Specifically, different H$_{2}$-ICl(B,v), D$_{2}$-ICl(B,v), H$_{2}$-I$_{2}$(B,v) and D$_{2}$-I$_{2}$(B,v) intermolecular vibrational levels are prepared. The subsequent ICl(B,v) and I$_{2}$(B,v) product-state distributions are then measured with rotational-state resolution. The roles of the geometry of the initially prepared complex and of ortho- and para-H$_{2}$ on the dynamics are extracted. Similar experiments were also performed to measure the binding energies of all of the conformers.
