WebNMR and EELS are commonly used for evaluating the structure of DLC and other carbon-containing materials. NMR is used to observe alterations in magnetic resonance frequencies that are associated with chemical bonding. The NMR signal is only obtained from C 13 atoms, which make up approximately 1.1% of all of the carbon atoms. 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.
