Hydroxyl radicals (OH) are important in many chemical systems, including combustion and atmospheric reactions, however experimentally measuring their velocities in specific internal quantum states has proved difficult. Now differential cross-sections for inelastic scattering of fully state-specified OH with He and Ar have been observed for the first time using velocity-map imaging in a crossed-molecular-beam arrangement.
