Resonance Raman studies of the elimination and transformation reaction of Durham polyacetylene.

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