DEPT NMR. What is it? What are the signal types, which signals are pointing down in DEPT and how to use it for solving NMR problems?

DEPT (Distortionless Enhancement by Polarization Transfer) ¹³C NMR Spectroscopy is a powerful technique used in organic chemistry to elucidate the structure of organic molecules.

Feb 11, 2023 · Understand the difference between 1D 13 C NMR and DEPT. There are many types of experiments that can be run using the NMR spectrometer, including gathering information from 13 C NMR spectra and while broadband decoupling gives a simpler spectrum, it loses information about neighbors.

Among these techniques is one called DEPT–NMR, for distortionless enhancement by polarization transfer, which makes it possible to distinguish between signals due to CH 3, CH 2, CH, and quaternary carbons. That is, the number of hydrogens attached to each carbon in a molecule can be determined.

Nov 19, 2015 · Distortionless Enhancement by Polarization Transfer (DEPT) is a double resonance pulse program that transfers polarization from an excited nucleus to another – most commonly 1 H → C.

The DEPT (Distortionless Enhancement by Polarization Transfer) experiment was designed to improve the sensitivity of NMR experiments on low-abundant and low magnetogyric ratio nuclei, X , such as 13 C or 15 N.

The DEPT (Distortionless Enhancement by Polarization Transfer) experiment is used to determine the multiplicity of carbon atoms, that is, whether they are C, CH, CH2, or CH3. The DEPT 135 experiment used at Columbia gives inverted CH2 and C groups.

Among these techniques is one called DEPT–NMR, for distortionless enhancement by polarization transfer, which makes it possible to distinguish between signals due to CH3, CH2, CH, and quaternary carbons. That is, the number of hydrogens attached to each carbon in a molecule can be determined.

DEPT (Distortionless Enhancement by Polazization Transfer) is a 13C detected, multiplicity analysis experiment that differentiates CH, CH2 and CH3 carbons from each other. Quaternary carbons are suppressed in the experiment.

The distortionless enhancement by polarization transfer (DEPT) experiment is slighlty more sensitive than APT and can fully separate the carbon signals.
