Zusammenfassung:
In the past, magnetic fields have been frequently used to orient liquid crystals and large components of biological cells. The availability of high magnetic fields up to 20 Tesla makes possible the relatively strong orientation also of diamagnetically anisotropic macromolecules or small molecular clusters. From the degree of magnetic alignment-detected optically - the persistence length of flexible polymers and the size of various molecular clusters has been determined with high precision. In particular, this new method has been used recently in order to study the following structural problems:

1. 1)|The rigidity of nucleic acids in various solutions
2. 2)|The lateral structural correlation within a phospholipid membrane
3. 3)|The degree of local order in liquid polymers.
