Isomerization and precursor conversion

In isomerization studies a continuous shift of the equatorial reflections from their cis positions to the 

A study on polyacetylene of the Naarmann-Theo-philou type [14] has been published by Djurado et al. [82], using both x-ray and neutron diffraction. This type of polyacetylene is characterized by a high value of the longitudinal coherence length, Z. n = 170 A, and a reduced rate of isomerization at 300 K compared to 

Shirakawa polyacetylene. A draw ratio of six has been obtained.
