Popis:	CH 3 , CH 2 , CH, and C, adsorbed on polycrystalline Co or Ni, are idendified and characterized by XPS and UPS with respect to peak positions and temperature regimes of existence. The species are generated by adsorption and subsequent dissociation of CH 3 Cl or CH 2 Cl 2 . Due to the early dissociation of the CC1 bond it is possible to study the CH n species and their stepwise dehydrogenation without interference. Constant and temperature independent peak positions over ranges of at least 50 K on Co and of about 40 K on Ni indicate that the peak maxima used for identification are generated by the respective single species and not by superimposition of two or more peaks of species drifting through the dehydrogenation.
