The interaction of hydrogen with surfaces plays a pivotal role in a range of applications, from the safe storage of rocket fuel to heterogeneous catalysis. One particular quantum-state which it was difficult to control was the rotational orientation of the molecule, which classically corresponds to whether the molecule is rotating like a helicopter or a cartwheel as it approaches the surface. In my talk, I will introduce a unique magnetic molecular interferometry technique which allows us to control and manipulate this, and demonstrate how it can be used to extract information about how the amplitude and phase of the rotational wavefunction of the molecules changes when they collide with the surface, before presenting an overview of the results that we have obtained using the technique.
