Distortionless Enhancement by Polarization Transfer

Doddrell and coworkers designed the DEPT sequence where the discrimination of J-coupled resonance lines relies on the flip angle beta rather than a refocusing delay delta in INEPT. Since the flip angle beta is independent of J, whereas the delay between pulses depends on J, the DEPT experiment is superior for spectral editing.

DEPT pulse sequence

Compared to the INEPT experiment, there are 180° pulses applied simultaneously with 90° pulses.
