The emission spectra of polyaeenaphthylene (PA&T) and polyvinyluaphthalene (PVN) tihus and solutions have heen compared at room temperature and 77Β°K. In organic glasses at 77'K, normal fluoresceuee and phosphorescence are observed for both polymers. Quenching of PAcN phosphorescence by piperylene in
~aet--The etfieiency of transfer from the triplet of polymethylvinylketone (PMVK) to naphthalene has been measured at 77Β°K. The critical distance of transfer according to Hirayama is 11.3 A. This is the usual value of Ro for exchange interaction without migration. Singiet energy transfer from the po
