Dynamics of reactive collisions by far wing laser light scattering

We report on our studies of the far wing absorption of laser light into the MgH2 reactive collision complex. We have measured the absorption profile leading to both the non‐reactive channel (Mg* formation) and into a specific ro‐vibrational state of the reactive channel (MgH (v‘=0, J‘=23) and have developed a simple theoretical model to explain some of the general features of the results.
