1. DEPT Spectra COSY Spectra HETCOR Spectra

2. Distortionless Enhancement by Polarization Transfer
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 angle Avoids overlapping multiplets

4. DEPT 45, 90, 135
Carbon type C null null null CH up up up CH2 up null down CH3 up null up

5. 2-Heptanone, CPD and DEPT-35
