A new and efficient broadband decoupling sequence is presented. It is based on the phase cycling of two pulses with small phase angles. The pulse width is 180 degrees +/- 30 degrees, and the phase angle is +/-10 degrees-12 degrees. The sequence contains 16 elements, and is called SPARC-16 as an abbr
A broadband hetemnuclear decoupling scheme for high resolution liquid phase NMR spectroscopy is described, based on adiabatic fast passage with a linear frequency sweep. It is shown that the flexible choice of shaping function for the radiofrequency amplitude profile allows the method to be adapted
In NMR of spins with I = 1/2 in an isotropic phase, it is demonstrated by simulation and experiment that virtually unlimited bandwidths can be decoupled effectively by using chirp pulses with linear frequency modulation for adiabatic inversion combined with phase-cycles and supercycles similar to th
