The results of velocity-map imaging experiments characterizing the vibrational predissociation dynamics of HCl dimer have been published in the Journal of Chemical Physics. The free and bound HCl stretch overtones were excited using an infrared laser and the monomer fragments detected using 2+1 REMPI. The correlated product-pair distributions show a strong propensity to maximize rotational excitation and minimize the recoil translational energy. The experimental results are compared with the predictions of various predissociation models.
