Reading Hydrogen Counts in 13C DEPT Spectra

13C DEPT spectra help chemists read how many hydrogens are attached to each carbon in a molecule. In proton-coupled carbon-13 spectra, broadband proton decoupling simplifies the signal, but it also removes information about the attached protons. DEPT, or distortionless enhancement by polarization transfer, restores that kind...

When carbon-13 spectra are simplified by broadband proton decoupling, structural information regarding the attached hydrogens is lost.

Distortionless enhancement by polarization transfer, or DEPT, is a double resonance technique that distinguishes carbons by the number of attached protons.

The DEPT experiment utilizes a complex pul...
