Performing quantum state selective experiments of molecule-surface collisions provides unique insight into the interaction potential. One particularly tricky molecular property to control and measure is the rotational projection states, i.e. the orientation of the rotational plane of the molecule. Previous data was mostly restricted to photo-excited/paramagnetic species. In this talk, I will describe the apparatus, proof-of-principle experiments, demonstrating control and measurements of the rotational projection states of ground state hydrogen molecules1, new experimental results for H2 colliding with ionic surfaces, and discuss the future of this new technique in terms of studying interaction-potentials and modifying the outcome of reactive molecule-surface collisions.
