The copolymers were synthesized by free-radical copolymerization of the corresponding monomers at several monomer feed ratios to obtain poly(VPA-co-VTri) copolymer electrolytes.

The analysis of high-resolution double-quantum nuclear magnetic resonance spinning sidebands for measuring dipolar couplings and internuclear distances in dipolar solids is described. For this purpose, the response of a dipolar-coupled spin system in a rigid solid is investigated with respect to high-resolution multiple-quantum experiments Let me go ahead and rewrite that.

Burdzhiev N, Ahmedova A, Borrisov B, Graf R. 13 C CPMAS NMR as a Tool for Full Structural Description of 2-Phenyl Substituted Imidazoles That Overcomes the Effects of Fast Tautomerization. NMR is an abbreviation for Nuclear Magnetic Resonance. An NMR instrument allows the molecular structure of a material to be analyzed by observing and measuring the interaction of nuclear spins when placed in a powerful magnetic field. Nuclear Magnetic Resonance NMR is based on the behavior of a sample placed in an electromagnet and irradiated with radiofrequency waves: 60 – 900 MHz (l ≈ 0.5 m) The magnet is typically large, strong, $$$, and delivers a stable, uniform field – required for the best NMR data A transceiver antenna, called the NMR probe, is 29 Si MAS NMR was performed on a Bruker 300 MHz spectrometer equipped with a 4 mm H/X probe and 10 kHz MAS spinning frequency.
