Solution NMR was possible on solvent-swollen samples containing less than 0.5% by weight EGDMA. Spectra confirm significant amounts of singly reacted EGDMA in fdly polymerized networks. Peaks arising from the two most likely stereochemical triads (syndi-and heterotactic) were identified but no ...
The underlying principles of solid-state NMR spectroscopy are outlined with an emphasis on the physical origins of the interactions that affect NMR spectra so that an understanding of the structural information they convey is clearly understood. The fund
NMR parameters such as signal chemical shift, intensity, line width, and shape were investigated in relation to the characteristics of gel beads such as the swelling ratio, the diameter, pore size, and crosslinking density. The relative intensity of the signal due to chloroform inside the gel ...

Optimum pH ranges and thermal treatment conditions have been established on the basis of extensive solution- and solid state NMR spectroscopies. The NMR spectra help identify the various types of local environments present in the sols, gels and glasses, thereby providing a mechanistic understanding of...
Similar results are also observed in the low-field nuclear magnetic resonance (NMR) measurements (Supplementary Fig. 8; Supplementary Note 4). Consequently, the PPDP gel electrolyte gives rise to a higher water retention ability than PVA gel electrolyte at solid state (Supplementary Fig. 9; ...
Solid-state 29Si NMR spectroscopy has been used to show that the matrixes containing ligands or complexes have comparable structures, independently from the employed spacer (n-propyl, n-hexyl, or n-oct... 展开 DOI: 10.1021/cm9601650 被引量: 56 ...
The molecular structures of the electrospun membranes and GPEs were acquired from 1H NMR spectra (Bruker, AVANCE III HD600 spectrometer with DMSO-D6 as solvent) and Fourier transform infrared spectroscopy (FTIR, AVTATAR, 370) based on dried KBr wafer in 500–4000 cm−1. The thermal ...
