An alternative setup for Magic Angle Oriented Spinning Spectroscopy is proposed. Samples were prepared by orienting lipid bilayers onto polymer films, which were wrapped into a spiral so as to fit into 4 or 7 mm MAS rotors. This geometry resulted in narrow line widths and a higher upper spinning limit when compared to the conventional MAOSS setup with stacked glass plates. Whereas orientational information was extracted from low spinning spectra, fast spinning will be applicable to high-resolution multidimensional NMR pulse sequences.
提出了一种用于魔角取向旋转光谱的替代装置。通过将脂质双层定向到聚合物薄膜上来制备样品,这些聚合物薄膜被缠绕成螺旋状以适合4或7毫米的魔角旋转(MAS)转子。与传统的带有堆叠玻璃板的魔角取向旋转光谱(MAOSS)装置相比,这种几何结构导致了更窄的线宽和更高的最高旋转极限。虽然取向信息是从低旋转光谱中提取的,但快速旋转将适用于高分辨率多维核磁共振脉冲序列。
