Ternpernture dependent ESR relaxation measurements made on the excited triplet state of pyrene-d-10 show ;L decrease in Tie with decrease in temperature from 300Β°K to SOOK. Optical measurements suggest the relnxation arises from exciton motion in the host crystal fluorene.
## Abstract **Summary:** The structural evolution of a metallocenic syndiotactic poly(propylene), sPP, with time has been studied. Due to the low syndiotactic content, the analyzed sPP sample can be easily quenched to a completely amorphous state. This amorphous sample, when left at room temperatur
