✦ Synopsis

In this article, we have applied solid-state 13 C NMR techniques, crosspolarization/magic-angle spinning (CP/MAS), and single-pulse 13 C NMR to characterize the NB conformation of the cyclo-olefin copolymer. The copolymers containing higher NB contents produce more NB blocks according to 13 C CP/MAS spectral analysis. In addition, NB-dyad-based conformations are able to induce peak splitting in the region of 49 -52 ppm.

Eighteen cyclopentadienyllithium complexes were studied by solid-state 7Li NMR spectroscopy. It is shown that the chemical shift gives information on the type of complex, i.e. whether the complex is a contact ion pair, a solvent-separated ion pair, a sandwich structure or a polymeric material.
