Anisotropic Rotational Diffusion

The molecular dynamics in solution for a series of cyclic and bicyclic hydrocarbon derivatives has been investigated by C-13 pulsed Fourier Transform nuclear magnetic resonance spin–lattice relaxation experiments. Molecular motion has been analysed in terms of an anisotropic rotational diffusion model, and an attempt has been made to assess the effects of structure on the observed rotational diffusion constants. Errors in the diffusion constants are discussed, and some of the other problems inherent in the use of these parameters to obtain structural information are outlined.

Walled Carbon Nanotubes

AbstractLithium intercalted carbon nanotubes have attracted considerable interest as perspective components for energy storage devices. We performed 13C Nuclear Magnetic Resonance spin lattice relaxation measurements in a temperature range from 4 K up to 300 on alkali intercalated Single Walled Carbon Nanotubes in order to investigate the modifications of the electronic properties. The density of states at the Fermi level were determined for pristine, lithium and cesium intercalated carbon nanotubes and are discussed in terms of intercalation and charge transfer effects.
