We report on nuclear magnetic resonance on single wall carbon nanotubes. Depending on the chemical preparation the electronic and dynamical properties of carbon nanotubes are presented and discussed. From a room temperature study of the spin lattice relaxation of carbon nanotubes prepared with vario

✦ Synopsis
Abstract
The tetraphenyl–metal, hexaphenyl–dimetal, and triphenylchloro–metal derivatives of the Group IV elements were examined using ^13^C NMR methods. Chemical shifts and metal–carbon coupling constants were obtained for all compounds studied.

## Abstract The proton and carbon‐13 NMR spectra of thirteen trialkylmetal derivatives of pyridine, several of which were previously unknown, have been recorded and analysed. The proton NMR spectra show variations in proton chemical shifts but not in proton‐proton coupling constants when the metal
## Abstract The diterpene trachylobane and a series of derivatives have been completely analysed by FT ^13^C NMR spectroscopy. All ^13^C frequencies for trachylobanol have been unambiguously assigned by experimental techniques, i.e. by proton single‐frequency selective decoupling and shift reagent
