Relaxation Measurements

The results of spin–lattice relaxation measurements are reported for carbonatotetramminecobalt(III) sulfate. The observed TI minima and activation energies, 1.9 and 4.3 kcal, for the reorientation of ammine groups are interpreted on the basis of hydrogen bonding effects.

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.
