Abstract
We present the results of optical investigations of transient patterns appearing during the reorientation of nematic LC in magnetic fields. The transition from a planar modulated director field to a metastable non-planar structure of twist-bend walls is observed. From the wavelen gths and characteristic rise times of the investigated patterns, the v alidity of the linearized mode selection theory is confirmed and visco elastic parameters are determined.
