Abstract
The transition from a spatially uniformly oscillating surface to the f ormation of chemical wave patterns has been investigated in the NO+CO reaction on Pt(100) using photoemission electron microscopy. This tran sition is associated with a discontinuous jump in the local oscillatio n frequency and can be described as a breakdown of global coupling cau sed by the presence of defects in the oscillating medium.
