Why are NMR peaks of flexible polymers usually broad? Is it due to the intramolecular proton J coupling among different repeating units? asked Sep 07 '14 at 19:30 timlo |
Answer: Conformational inhomogeneity. Try to cool it down to 200 K and then look at spectrum :) answered Sep 09 '14 at 10:05 Arkadiusz Leniak |
