“…[11] Such an optimization can include the basic characteristics of the resonance circuit in the form of the transfer function [12,13] but this time-consuming approach needs to be repeated, ideally,f or each sample and temperature as changing the experimental conditions changes the transfer function. [14,15] A related approach which has specifically been used to suppress effects of phase transients is the experimental optimization of pulse sequence parameters that can partially counteract them [5,16] using ag rid search.

“…Another approach is the direct optimization of pulse sequences on the spectrometer which also takes the characteristic of the resonance circuit into account. [14,15] A related approach which has specifically been used to suppress effects of phase transients is the experimental optimization of pulse sequence parameters that can partially counteract them [5,16] using ag rid search. In all these approaches the obtained optimized pulse sequences will be specific to the transfer function of the experimental setup and must be reoptimized if the experimental setup or the tuning and matching changes.I nt he latter two cases,t he optimization should take place on the sample to be studied which is challenging for biomolecules with limited signal-to-noise ratio.A sa na pproximation, at est sample with sufficient signal-to-noise could be used.…”

“…The first strategy to average out homonuclear proton-proton interactions using radio-frequency (rf) fields in static samples was suggested by Lee and Goldburg (Goldburg and Lee, 1963;Lee and Goldburg, 1965). Since then, many homonuclear decoupling sequences have been developed including solid-echo based sequences (WAHUHA (Waugh et al, 1968), MREV (Mansfield and Grannell, 1971;Rhim et al, 1973), BR-24 Rhim, 1979a, 1979b)), time-reversal sequences (Rhim et al, 1971), C-and R-symmetry based sequences (Levitt, 2007;Madhu et al, 2001;Paul et al, 2010), tilted magic-echo-based sequences (Gan et al, 2011;Lu et al, 2012;Nishiyama et al, 2012), and computeroptimized sequences like DUMBO (Grimminck et al, 2011;Halse and Emsley, 2012;Sakellariou et al, 2000;Salager et al, 2009). Each of these sequences has their own advantages and disadvantages in terms of robustness for different MAS spinning regimes and requirements for the radio-frequency field strength.…”

“…The theoretical description of Lee-Goldburg sequences can be done within the framework of average Hamiltonian theory (AHT) (Ernst et al, 1990;Haeberlen, 1976) or Floquet theory (Leskes et al, 2009(Leskes et al, , 2010Scholz et al, 2010;Shirley, 1965). Such a description has been used to predict the first-order resonance conditions between the MAS frequency and the modulation frequency of the pulse sequence as well as the magnitude of the non-vanishing second-order dipole-dipole cross terms.…”
