Abstract
Recently we developed an efficient broadband decoupling sequence called SPARC-16 for liquid crystals [J. Magn. Reson. 130, 317 (1998)]. The sequence is based upon a 16-step phase cycling of the 2-step TPPM decoupling method for solids [J. Chem. Phys. 103, 6951 (1995)]. Since then, we have found that a stepwise variation of the phase angle in the TPPM sequence offers even better results. The application of this new method to a liquid crystalline compound, 4-n-pentyl-4′-cyanobiphenyl, and a solid, l-tyrosine hydrochloride, is reported. The reason for the improvement is explained by an analysis of the problem in the rotating frame.
