The acyl chain of spin-labeled fatty acids intercalates between the lipid hydrocarbon chains in hexagonal and micellar phases with the carboxyl group anchored at the lipid water interface. The spectra are characteristic of anisotropic motion and cannot be distinguished from the spectra of these probes in lamellar dispersions. In the hexagonal and micellar phases the molecular motion of the spin label increases as it is moved further away from the carboxyl group, similar to the behavior in the lamellar phase (Jost et al. (1971) J. Mol. Biol. 59, 77-98). The similarity in packing of the acyl chains in the hexagonal and lamellar phases suggests that localized regions of hexagonal phase are compatible with a bilayer matrix.
自旋标记脂肪酸的酰基链插入六方相和胶束相的脂质烃链之间，羧基锚定在脂质-水界面。这些光谱具有各向异性运动的特征，无法与层状分散体中这些探针的光谱区分开来。在六方相和胶束相中，自旋标记的分子运动随着其远离羧基而增加，这与层状相中的行为相似（约斯特等人，（1971年）《分子生物学杂志》59卷，77 - 98页）。六方相和层状相中酰基链堆积的相似性表明，六方相的局部区域与双层基质兼容。
