Carbon-13 NMR Spectroscopy in Organic Chemistry

This concept covers Carbon-13 NMR spectroscopy as a structure-elucidation technique in organic chemistry, explaining that because only ~1% of carbon is the NMR-active Carbon-13 isotope, a proton-decoupled spectrum is used to eliminate splitting and yield one singlet signal per unique carbon. It relates to the broader discipline of NMR spectroscopy by paralleling proton NMR's signal-counting principle while differing in chemical shift range and the loss of quantitative peak integration due to the decoupling method.
