DEPT NMR vs APT NMR: Which is Better?
Distortionless Enhancement by Polarization Transfer NMR ( DEPT NMR) and Attached Proton Test NMR (APT NMR) are 13C NMR experiments that reveal the number of protons that are attached to individual 13C carbon atoms in a molecule.Together they answer the question, “Does this peak represent a primary (methyl or -CH3 group), secondary (methylene or -CH2 group), tertiary (methine or -CH group), or quaternary carbon?” Such knowledge is key for structural elucidation, especially for more complex molecules. Let’s take a look at the advantages and...
