Need for high resolution 2D spectra 13C NMR spectra provide wide range chemical shift, and it suggests that can easily distinguish each signals. But carbon resolution of 2D spectra such as HSQC and HMBC is worse than 1D 13C spectra due to small data points. In order to analyze a compound with close 13C chemical shifts, a high resolution 2D spectrum is required frequently. In this document, some improvements to distinguish each signals on 13C axis of 2D hetero nuclear experiments are presented.

High sensitivity and quantitative 13C measurements using "Q-POMMIE" POMMIE (Phase Osacillations to Maximize Editing) is a 13C experiment that, like the more familiar DEPT experiment, utilizes polarization transfer to enhance the intensities of the 13C signals. However, unlike DEPT, POMMIE edits the spectrum by varying pulse phase rather than adjusting pulse flip angle.
