Abstract
Among organic-chain molecules, normal alkanes [CH3(CH2)n-2CH3; n<40] provide model systems for studying the effect of molecular flexibility on diffusion in adsorbed films. Quasielastic neutron scattering was used to study the alkane films on a graphite substrate, emphasizing the dependence of the observed spectra on the molecular length. Results indicate that quasielastic neutron scattering can be used to study the diffusive motion in prototypical polymers in the time domain of 1-40 ps.
