NMR of Paramagnetic Molecules (eBook, PDF)

Redaktion: Berliner, Lawrence J.; Reuben, Jacques

• Format: PDF

Produktbeschreibung

The first of a two volume set, Volume 12 provides a long-awaited compilation of NMR theory to paramagnetic molecules. International experts report the latest developments in NMR methodology as applied to strongly relaxed and shifted resonances, detail the theoretical aspects of paramagnetic shift and relaxation, and discuss the interpretive bases of these molecular properties in relation to the structure and function of various paramagnetic molecules.
