Abstract
The elimination and transformation reaction of. Durham polyacetylene has been monitored “by resonance Raman spectroscopy. The resonance Raman and photoluminescence spectrum from short cis segments, present in the pre-cursor polymer, has been recorded. A distribution of cis polyacetylene sequence lengths has been observed from Raman measurements made at different time intervals as the reaction proceeds, using λg 647-1nm. The μ2 values recorded gradually decrease as the reaction proceeds the limiting value of 1472 cm−1 is significantly less than the 1450–1460 cm−1 values reported for the Shirakawa polymer.Keywords
