By Robert B. Bates,William A. Beavers

With the appearance of Fourier remodel spectrometers of serious sensitivity, it has turn into functional to acquire carbon-13 nuclear magnetic resonance (C-13 NMR; l3C NMR; CMR) spectra normally on natural molecules, and this method has develop into one of many maximum application in settling on buildings of natural unknowns. while the standard spectrometric recommendations­ proton magnetic resonance (H-I NMR; IH NMR; PMR), infrared (lR), mass (MS), and ultraviolet (UV)-do no longer easily demonstrate a compound's constitution, a C-13 NMR spectrum will usually supply adequate more information to yield it unequivocally. With this in brain, the current paintings used to be designed to offer complex undergraduates, graduate scholars, and training chemists a operating wisdom of and facility with using this important strategy. a few familiarity with different spectrometric options is thought (recommended publication: Silverstein, Bassler, and Morrill, Spectrometric identity of natural Compounds), yet no previous wisdom of C-13 NMR -which is handled very frivolously, if in any respect, within the general simple natural texts-is beneficial. A dialogue of C-13 NMR spectroscopy is by way of one hundred twenty five difficulties, each one along with a molecular formulation, sorts of C-13 NMR spectra (partially and entirely proton decoupled, with connecting strains to facilitate multiplicity assignments), an built-in H-I NMR spectrum, and an important IR, UV, and MS info. those difficulties were very conscientiously ready, completely validated through scholars on the college of Arizona, and we think that only a few mistakes remain.
