Overtone vibration-laser double resonance measurements have provided new data on vibrational and rotational relaxation in HF(v=2). These experiments determine the magnitudes of the total vibrational relaxation rate constants for HF (v=1 and 2) as well as their temperature dependences. Detailed analysis yields the variation of the branching between competing V-V and V-TR pathways. Rotational relaxation data come from these measurements as well. The temporal evolution of individual rotational states observed in the double resonance studies provides level-to-level energy transfer rate constants when analyzed using an iterative fitting scheme which incorporates scaling relations among the rate constants.
