13C spectra of DMPC/DHPC bicelles at 37°C measured with different heteronuclear decoupling sequences. The proton decoupler RF field strength was set at 20 kHz. The RF decoupler frequency was set to a value that resulted in an optimal resolution for the crowded chain-carbon region when CW irradiation was used. The pulse durations were optimized for WALTZ-16 and FLOPSY-8 sequences, while both pulse durations and RF phase shifts were optimized for TPPM and SPINAL-64 schemes. The spectral region containing signals from the lipid head group and glycerol sites is expanded for an easy comparison of spectra obtained using the FLOPSY and SPINAL decoupling sequences.
