1 Αυγ 2024 · Today, the focus will be on specific regions of chemical shift characteristic for the most common functional groups in organic chemistry. Below are the main regions in the 1 H NMR spectrum and the ppm values for protons in specific functional groups:
Use this reference table to find the coupling values and chemical shifts of our NMR (deuterated) solvents. Melting and boiling points, molecular weight, density, and CAS number are also listed.
It follows the same basic concepts, i.e., it provides a representative, albeit limited set of reference data for the interpretation of 13C NMR, 1H NMR, IR, mass, and UV/Vis spectra. We also added a new chapter with reference data for 19F and31P NMR spectroscopy and, in the chapter on infrared spectroscopy, we newly refer to important Raman bands.
Please note that the values given in the tables are temperature- and partly concentration-dependent and therefore represent average values only. Proton Mult.

Nuclear Magnetic Resonance (NMR) is a commonly used technique for organic compound structure determination. In 1 H NMR, applying an external magnetic field causes the nuclei spin to flip.
