WebJun 24, 2015 · Decoupling is the simplification of an NMR spectrum by irradiating the sample with radio-frequencies to remove the splitting caused by protons. It is especially important in ""^13"C" NMR spectra. Coupled Spectra The ""^13"C" signals are split by the H atoms attached to them. These splittings are much larger than in ""^1"H" spectra (J_("C-H") … Web1. Background. Over the past fifty years nuclear magnetic resonance spectroscopy, commonly referred to as nmr, has become the preeminent technique for determining the structure of organic compounds. Of all the spectroscopic methods, it is the only one for which a complete analysis and interpretation of the entire spectrum is normally expected.
