Monitoring of the molecular motions and secondary structures of gliadin (Gli) and glutenin (Glu) in blends with 10, 20, 30, and 40% glycerol was performed by solid-state (SS) and time domain (TD) NMR spectroscopy. Increasing the glycerol content incr

NMR Methods for Characterization of Synthetic and Natural Polymers ISBN: 9781788014007
This chapter is dedicated to the discussion of some dipolar based solid-state NMR methods that can be used to probe molecular motions in polymers. The focus is on methods to study the so-called intermediate regime motions, i.e., occurring with motion

A composed Gaussian local field is proposed to describe the effect of molecular motions on NMR signals of SIn units (e.g., CHn or NHn), based upon the well-know Anderson–Weiss (AW) approximation. The approach is exemplified on constant-time recoupl

Carbon-proton dipole-dipole couplings between bonded atoms represent a popular probe of molecular dynamics in soft materials or biomolecules. Their site-resolved determination, for example, by using the popular DIPSHIFT experiment, can be challenged

A specific separated-local-field NMR experiment, dubbed Dipolar-Chemical-Shift Correlation (DIPSHIFT) is frequently used to study molecular motions by probing reorientations through the changes in XH dipolar coupling and T 2 . In systems where the co

In this article, we evaluate the use of simple Lee–Goldburg cross-polarization (LG-CP) NMR experiments for obtaining quantitative information of molecular motion in the intermediate regime. In particular, we introduce the measurement of Hartmann–

Neste trabalho exploramos o uso de sequências de pulsos de Ressonância Magnética Nuclear de Estado Sólido (RMN-ES) que utilizam o acoplamento dipolar magnético heteronuclear para o estudo de reorientações de segmentos moleculares no regime int
