Abstract:We have used NMR to determine the structure of acetylene (HC(TBOND)CH) adsorbed at room temperature on small platinum particles by studying the ('13)C-('13)C, ('13)C-('1)H, and ('1)H-('1)H dipolar interactions among the nuclei in the adsorbed molecules. We find a model of 77% CCH(,2) and 23% HCCH to be the only one consistent with all of our data. The C-C bond length of the majority species, CCH(,2), is determined as 1.44 (+OR-) 0.02 (ANGSTROM), midway between a single and double bond, suggesting that both carbon atoms bond to the surface.
