WebFeb 7, 2024 · Concept: 13 C NMR:. The Carbon-13 nuclear magnetic resonance or 13 C NMR spectroscopy is the application of nuclear magnetic resonance spectroscopy to carbon (C). 13 C NMR spectroscopy helps to identify the nature or environment of C atoms in organic molecules just as 1H NMR spectroscopy helps to detect the H atoms. The nature or … WebNov 17, 2024 · NMR is great for any type of nucleus that has an odd mass number. For most organic chemistry courses, you collect 1 H (proton) and 13 C (carbon-13) NMR spectra. Samples are usually in solution, because allowing the molecules to move freely will help average their signals. Other techniques are possible.
