|a Heteronuclear dipolar decoupling is an essential requirement for extracting structural information from the (13)C NMR spectra of liquid crystals. Efficient schemes for heteronuclear dipolar decoupling in such systems are formulated here by supercycling SW(f)-TPPM, a sequence introduced recently for this purpose in rotating solids. These sequences are compared with two other commonly used decoupling schemes in liquid-crystal NMR, SPINAL-64 and SW(f)-TPPM, by analyzing the intensities of various resonances in the proton decoupled (13)C spectrum of the liquid-crystal 4-n-pentyl-4'-cyanobiphenyl (5CB). The effectiveness of the decoupling programs with respect to experimental parameters such as RF field strength, decoupler offset frequency and phase angle is also presented
