Ethylene on a surface : C 2 D 4− x H x ( x =0–4) species that result from H/D exchange reactions on a Pt(111) surface are quantitatively identified by using a Cs + reactive ion scattering method (RIS). Two temperature‐dependent pathways are identified for the exchange process (see scheme; a: T <265 K; b: T >265 K).
