15.7 Complex Splitting | NMR | Organic Chemistry

Chad explains the nature of complex splitting in NMR Spectroscopy, how to predict when complex splitting will occur, and how to predict complex splitting patterns in H NMR spectra. He includes a table for alkyl and geminal and vicinal coupling constants commonly presented in undergraduate organic chemistry. He analyzes three examples of complex splitting and shows how a “splitting tree” can be constructed to determine the number of peaks in an NMR signal where complex splitting occurs. Examples of common complex splitting patterns such as a doublet of doublets and multiplets are covered.
