WebFeb 2, 2024 · NMR experiments are carried out in static magnetic fields, which can limit the usefulness of NMR spectra. The magnetic field can also be increased during experiment execution, which affects the nuclear spin level’s Boltzmann population and Larmor frequency. This in turn results in increased intensity of NMR signals. WebJul 14, 2024 · For example, the 1 H NMR shows you the NMR peaks that represent particular functional groups in a molecular formula (specifically, carboxylic acids, aldehydes, and aromatic rings). You can then use integration ratios (plus information about the degrees of unsaturation and the molecule's location in the IR [infrared] spectrum) to determine all the …
