On page 2543, the bipolar scheme uses two gradient pulses for encoding, and two other gradient pulses for decoding. Thus, Equation 1 should be S/S0 = exp{-D4k2(D + 6t)}, rather than S/S0 = exp{-Dk2(D + 6t)}, as published. The incorrect expression would lea ...
We report on NMR evidence about a novel effect in La1-xCa xMnO3+δ systems with cation deficience. We show that in the low-Ca-doping regime, these systems exhibit a very strong hyperfine field at certain La nuclear sites, which is not present in the stoichi ...
The experimental performance of the phase modulated decoupling schemes SDROOPY-1 and SPINAL64 is investigated for heteronuclear dipolar decoupling in solid-state magic-angle-spinning nuclear magnetic resonance (NMR), in comparison with existing decoupling ...
The accuracy of determination of tensor parameters measured using solid-state nuclear magnetic resonance is investigated. In particular, the reliability of the determination of the anisotropy and the asymmetry parameter of the chemical shift is calculated ...
Using a refocused INADEQUATE NMR experiment we show that homonuclear carbon-carbon through-bond correlations can be obtained in disordered organic solids where the line widths greatly exceed the value of the scalar coupling. The feasibility of the experime ...
A new global analysis of EPR, 17O NMR relaxation and chemical shift and 1H NMRD profiles with physically meaningful parameters for [Gd(DOTA)(H2O)]− and for [Gd(DTPA)(H2O)]2− in aqueous solution is presented (DOTA=1,4,7,10-tetraaza-1,4,7,10-tetrakis(carboxy ...
A new solid-state NMR experiment, J-WISE, is presented for studying local mobility in solids with atomic resolution. The experiment correlates the wide-line proton spectrum with the isotropic chemical shift of carbon-13 via the J coupling between both nucl ...
An approach for enhancing the NMR sensitivity of the central transition of spin-3/2 nuclei is presented. Through selective excitation of the satellite transitions using a fast 180 degrees phase alternating pulse train during magic-angle spinning a selectiv ...
The performance of deuterium-carbon correlation (DECOR) spectroscopy for the assignment and measurement of deuterium quadrupolar couplings in fully deuterated liquid crystalline phases is analyzed. The experiment relies on a broadband polarization transfer ...
The translational diffusion coeff. of an integral membrane protein/surfactant complex has been measured using a novel pulsed field gradient NMR method. In this new approach, the information about the localization of the mols. is temporarily stored in the f ...
