n -alkanes on Pt(111) and on C ( 0001 ) ∕ Pt ( 111 ) : Chain length dependence of kinetic desorption parameters

We have measured the desorption of seven small n -alkanes ( C N H 2 N + 2 , N = 1 - 4 , 6 , 8 , 10 ) from the Pt(111) and C(0001) surfaces by temperature programed desorption. We compare these results to our recent study of the desorption kinetics of these molecules on MgO(100) [ J. Chem. Phys. 122...
