Description
The authors have used NMR to determine the structure of C2H2 adsorbed at room temperature on small platinum particles by probing the 13C-13C, 13C-1H, and 1H-1H dipolar interactions among the nuclei in the adsorbed molecules. They find a model of (77 +- 7)% CCH2 and (23 +- 7)% HCCH. The C-C bond length of the CCH2 is 1.44 +- 0.02 A, midway between a single and double bond, suggesting that both C atoms bond to the surface
