By E. Breitmaier

E. Breitmaier, W. Voelter Carbon-13 NMR Spectroscopy High-Resolution equipment and functions in natural Chemistry and Biochemistry 3rd, thoroughly revised variation New ideas and elevated use of pcs have ended in speedy improvement in 13C NMR spectroscopy with stronger instrumental sensitivity and more desirable caliber of the spectra. This necessitated a whole revision while the 3rd version of this profitable monograph used to be ready. the recent equipment defined comprise these for multiplicity research and two-dimensional homo- or hetero-nuclear shift correlations. As within the moment variation, the authors survey the big variety of 13C NMR functions to natural molecules and normal items in a consultant and systematic instead of an exhaustive means. New sections approximately coupling constants, organophosphorus and organometallic compounds in addition to artificial polymers were further. The scope is still restricted to high-resolution tools and molecular structures.
