However, carbon NMR has a number of complications that are not encountered in proton NMR. Carbon NMR is much less sensitive than1H NMR since the major isotope of carbon, the12C isotope, has a spin quantum number of zero and so is not magnetically active. Only the much less common13C isot...
Chapter NMR in Chemistry pp 84-107 Carbon-13 NMR Spectra William KempAffiliated withHeriot-Watt University Abstract The chemical shift range of carbon-13 resonances is so wide (more than 200 ppm for simple functional classes) that most compounds show a separate signal for each different ...
The PFT 13C NMR spectra of some representative 1-azirines are discussed. Two striking features are the large 13C1H spin coupling constants and the diagnostic chemical shift of C3.doi:10.1002/mrc.1270060905NairJohn Wiley & Sons, Ltd.Magnetic Resonance in Chemistry...
