Learn how Carbon-13 NMR spectroscopy analyzes molecular structure through chemical shifts, equivalent carbons, and spectral interpretation.
Why There Is No Splitting Carbon 13C NMR13C NMR Chemical ShiftA Few Words About Interesting Features and Exceptions in 13C NMRCarbon nucleus resonates at a different frequency range than proton does, which makes it possible to have all the signals as singlets. However, you need to know that signal splitting in 13C NMR by neighboring hydrogens does occur which leads to complicated splitting patterns. And that is why a technique called broadband decoupling is used. MoSee more on chemistrysteps NIST Chemistry WebBook
