摘要：

In two homologous series of bi-swallow tailed compounds transitions between lamellar (SmC), columnar (Col(rect)) and three-dimensional (T) phases have been studied by X-ray and NMR-methods. The NMR studies yield the conformation of the molecule, whereas the X-ray studies of monodomains provide information about die lattice type and the symmetry.
