To identify the CH 2 signal as the one that appears as a negative signal in the DEPT-135 spectrum and the CH 3 signal as the one that appears as a positive signal in the DEPT-135 spectrum but does not appear in DEPT-90 spectrum. Concept introduction: CH carbon signals appear normally in the DEPT-90 spectrum. CH 2 appears as a negative signal in the DEPT-135 spectrum. CH 3 signals appear as a positive signal in DEPT-135 spectra but not in the DEPT-90 spectrum. Signals of carbon without any protons do not appear in DEPT spectra.
