We present a novel sampling strategy, interleaving acquisition of multiple NMR spectra by exploiting initial polarization subsequently fromH andH spins, taking advantage of their differentT1relaxation times. DifferentH- andH-polarization based spectra are in this way simultaneously recorded improving either...

Ergodicity and efficiency of cross-polarization in NMR of static solids.
J Magn Reson. 2011 Apr;209(2):161-6

Cross-polarization transfer is employed in virtually every solid-state NMR experiment to enhance magnetization of low-gamma spins. Theory and experiment is used to assess the magnitude of the final quasistationary magnetization amplitude. The many-body density matrix equation is solved for relatively large (up to N=14) spin systems without the...

Repetitive cross-polarization contacts via equilibration-re-equilibration of the proton bath: sensitivity enhancement for NMR of membrane proteins reconstituted in magnetically aligned bicelles
Repetitive cross-polarization contacts via equilibration-re-equilibration of the proton bath: sensitivity enhancement for NMR of membrane proteins reconstituted in magnetically aligned bicelles

Thermodynamic limit of magnetization corresponding to the intact proton bath often cannot be transferred in a single cross-polarization contact. This is mainly due to the finite ratio between the number densities of the high-...
Recovering lost magnetization: polarization enhancement in biomolecular NMR
Recovering lost magnetization: polarization enhancement in biomolecular NMR
Abstract Experimental sensitivity remains a major drawback for the application of NMR spectroscopy to fragile and low concentrated biomolecular samples. Here we describe an efficient polarization enhancement mechanism in longitudinal-relaxation enhanced fast-pulsing triple-resonance experiments. By recovering undetectable 1H polarization originating from longitudinal relaxation during the pulse sequence, the steady-state 15N polarization becomes enhanced by up to a factor of ~5 with respect to thermal...
