摘要：

We present a new smooth amplitude-modulated (SAM) method that allows to observe highly resolved H-1 spectra in solid-state NMR. The method, which works mainly at fast of ultra-fast MAS speed (nu(R) > 25 kHz) is complementary to previous methods, such as DUMBO, FSLG/PMLG or symmetry-based sequences. The method is very robust and efficient and does not present line-shape distortions or fake peaks. The main limitation of the method is that it requires a modern console with fast electronics that most be able to define the cosine line-shape in a smooth Way, Without any transient. However, this limitation mainly occurs at Ultra-fast MAS where the rotation period is very short. (c) 2008 Elsevier Inc. All rights reserved.
