| Abstract: | Multiple quantum spin counting is shown to yield an upper limit ofn = 6 for strongly bound, rigid intermediates C m H n in the reaction of ethylene over Ru/SiO2. The results eliminate the possibility of major components of such intermediates being polymer-like coke precursers. A precurser to 2-butene is one possible intermediate. |
