6.7: ¹H NMR Spectra and Interpretation (Part II)
2021年12月16日 · In fact, the 1H NMR spectra of most organic molecules contain signals that are ‘split’ into two or more peaks that is called splitting (or coupling). The spectra with peak splitting may looked more complicated, however, this splitting behavior provides very useful information about the structure of a compound.
