Presentation Transcript

  1. DEPT SpectraCOSY SpectraHETCOR Spectra

  2. DEPT-90, DEPT-135 Distortionless Enhancement by Polarization Transfer • Preferred procedure for determining # protons attached to carbons • Variable proton pulse angle q is set at 90o and 135o • In DEPT-90, only CH shows. In DEPT-135, CH2’s are phased down, CH and CH3 are phased up

  3. Adjustment of 1H pulse angleAvoids overlapping multiplets

  4. 2-Heptanone, CPD and DEPT-35
