摘要：

The performance of a supercycled SWf-TPPM sequence for heteronuclear dipolar decoupling in solid-state NMR is analyzed here. The decoupling performance of this sequence with respect to experimental parameters, such as, the phase angle, proton offset and MAS frequency is studied. A comparison is made with two other commonly used decoupling schemes in solid-state NMR namely, SPINAL-64 and SWf-TPPM, on a sample of U-C-13-labeled tyrosine. Our results show that supercycled SWf-TPPM performs better than the former sequences. Also, numerical spin dynamics studies are presented which support the experimentally observed efficiency in the decoupling. (C) 2011 Elsevier Inc. All rights reserved.
