聚氧乙烯-六氟砷酸锂复合物不同结晶结构的13C谱归属
Structures of Crystalline Poly(ethyl oxide)/LiAsF6 Complexes Determined by Solid-State High-Resolution13C Nuclear Magnetic Resonance
摘要
Abstract
Depending on the annealing temperature, PEO/LiAsF6complex can form two different crystalline structures. The13C NMR spectra of both structures show high spectral resolution. In this study, 2D exchange13C experiment and13C fp-RFDR (finite-pulse radio-frequency-driven recoupling) DQ-SQ (double quantum-single quantum) experiment were used to assign the resonances of crystalline PEO/LiAsF6complexes. The results are useful for better understanding of the molecular motions in different crystalline structures.关键词
