尽管低温下核磁共振谱展宽到2 T，但受抑等边三角形自旋管CsCrF 4的基态仍被一层面纱所掩盖。为了用~（19）F-NMR研究有序态下的自旋结构，我们测定了顺磁态下每三个氟位的各向异性超精细耦合张量。测量场被提高到10 T以实现最高分辨率。用所得的超精细张量进行初步分析，发现在ab平面上的120°型结构原型与有序态的NMR谱不符合雅阁。
The ground state of the frustrated equilateral triangular spin tube CsCrF4is still hidden behind a veil though NMR spectrum broaden into 2 T at low temperature. In order to investigate the spin structure in an ordered state by19F-NMR, we have determined the anisotropic hyperfine coupling tensors for each three fluorine sites in the paramagnetic state. The measurement field was raised up to 10 T to achieve highest resolution. The preliminary analysis using the obtained hyperfine tensors has shown that the archetypal 120°-type structure inab-plane does not accord with the NMR spectra of ordered state.
