Ultraviolet photoemission spectroscopy s:udics indicate that acetylene chcmisorbs on Pd( 111) and Pt(I 11) as x-bonded acetylene for T 5 180 K but upon warming (or room tcmpcraturc exposure) forms a new surface species. We identify the electronic structure of this new phase as being characteristic o
