WebThe DEPT-135 gives signals of all protonated carbons, but CH and CH3 signals are positive, while CH2 peaks are negative. The signals of quaternary carbons are absent in all the DEPT spectra. By combining the DEPT-45, DEPT-90 and DEPT-135 spectra, it is possible to determine multiplicity of each carbon signal. What is DEPT spectrum? WebDEPTQ is similar to the DEPT experiment but it also allow us to detect non protonated carbons. Below, the different carbon signals observed on a DEPTQ and on a DEPT are detailed. Blue and red indicate signal phase up or down respectively.
