It's all in the spin : The initial sticking probability of O 2 on a CO‐precovered Pd(100) surface and the rate of CO 2 production are strongly affected by the alignment of the incoming molecules. Whereas O 2 molecules impinging with cartwheel‐like motion can stick in small holes, molecules moving with helicopter‐like motion need a large array of free sites (see picture).
