The theoretically developed Attached Proton Test (APT) and Distortionless Enhancement by Polarization Transfer (DEPT) curves for methane were compared with the corresponding experimentally measured data for13C enriched methane. As expected, in both cases the CH4curves have a similar shape than the corresponding CH2curves and show a minimum intensity when τ =1/2J.In the APT case the CH2curve takes larger values than the CH4 curve except at τ =0, 1/2Jand1/Jvalues where they have the same intensity. In the DEPT experiment, the maximum polarization transfer for CH4takes place at τ =1/6Jand5/6J, while for CH2this happen at τ =1/4Jand3/4J.This fact could be useful to distinguish the CH2and CH4signals using APT and DEPT experiments.
