Two-Pulse Phase Modulation Based Decoupling Schemes for Removing Heteronuclear Spin Interactions in the NMR Spectroscopy of Isotropic Systems: An Analysis Using Experiments and Numerical Simulations

Figure 2

The relative intensities of the decoupled 13C spectra of benzene at an RF power of 2.85 kHz using (a) TPPM, SWf-TPPM-11, 7, 6, 5, and 4 decoupling sequences at a phase angle of 15° and (b) WALTZ-16, MLEV-16, and GARP decoupling sequences. The proton offset varies between 2 and 12 ppm with respect to TMS.
