In this paper some effects of dynamical coupling between two interaction-carrying vectors on the internal auto- and cross-correlation functions are investigated in the limit of small amplitude motions. A linearized Langevin approach allows the derivation o ...
The reaction of [Ta(=CHtBu)(CH(2)tBu)(3)] or [CpTa(CH3)(4)] with a silica partially dehydroxylated at 700 degreesC gives the corresponding monosiloxy surface complexes [(=SIO)Ta(=CHtBu)(CH(2)tBu)(2)] and [(=SiO)Ta(CH3)(3)Cp] by eliminating a a-bonded lig ...
A new expt. allows the identification of residues that feature slow conformational exchange in macromols. Rotations about dihedral angles that are slower than the global correlation time tc cause a modulation of the isotropic chem. shifts of the nuclei. If ...
A new method for selective excitation in biomol. NMR uses two-fold single-transition cross-polarization between protons and nitrogen-15 or carbon-13 nuclei. Switching the frequencies between the forward and backward transfer steps allows one to select a mu ...
We present a new solid-state nuclear magnetic resonance experiment that yields, under CRAMPS decoupling conditions, a significant reduction in proton line widths for powdered organic solids. This experiment which relies on a constant-time acquisition of th ...
We performed an Eu153 and Eu151 NMR study of EuO and Gd doped EuO using a home-made spectrometer designed to measure signals with fast spin-spin relaxation times. We determined and described the broadening mechanisms giving rise to the structure in the lin ...
In this paper we demonstrate experimentally that the continuously phase-modulated homonuclear decoupling sequence DUMBO-1 is suitable for high-resolution proton NMR spectroscopy of rigid solids. Over a wide range of experimental conditions, we show on the ...
A new NMR method has been designed for the measurement of the longitudinal relaxation rates of both donor and acceptor nitrogen-15 nuclei in Watson-Crick base pairs in 15N-enriched nucleic acids. The expt. was applied to a 22-nucleotide RNA hairpin. The le ...
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 ...
In the present paper, we present a complete characterization of the propylene sulfide-ethylene glycol triblock copolymers (PPS-PEG) at a mol. level, and as lyotropic aggregates, with the precise localization of the hydrophilic/hydrophobic border of their v ...
