1 sie 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:
predict the approximate chemical shifts of each of the protons in an organic compound, given its structure and a table of chemical shift correlations.
Overview of typical 1H NMR shifts. Note: alkene region modified from earlier handout.

Most 1 H chemical shifts fall within the range 0 to 10 δ, which can be divided into the five regions shown in Table 13.2. By remembering the positions of these regions, it’s often possible to tell at a glance what kinds of protons a molecule contains. Table 13.2 Regions of the 1H NMR Spectrum.
