For the discussion of orientional states in liquid crystals, quadrupolar (2H NMR) and dipolar (1H NMR) interactions have mainly been exploited. There have also been attempts to describe the individual (regarding di β erent positions in a molecule) orientation and order by means of chemical shift info
## Abstract The results of a study of the relation between the oriented structure and drawn Poly(Ξ΅βcaprolactone) specimens including CaCO~3~ particles and their dynamic mechanical properties are presented. The loss elasticity, __Eβ³,__ showed almost the same curve for both undrawn sheets and drawn s
