Quantum-state-selected molecular beam allows us to investigate the effects of molecule's orientation, rotation, vibration and spin states on gas-surface reactions. Using a single spin-rotational state-selected O₂ beam, we have clarified how the alignment and electron spin of an impinging O₂ affect its adsorption and/or scattering processes. In this talk, I will present the alignment-resolved O₂ chemisorption experiment on stepped Pt surfaces and the development of a nuclear-spin/ rotational state selected H₂ beam.
