The fluorescence spectra of poly(2-vinylpyridine)s (P2VPs) were measured in solution at room temperature in the presence of trifluoroacetic acid(TFA) as a function of average degree of polymerization (D-P). All protonated P2VPs exhibited a dimer-like excimer and normal excimer fluorescence around 32

It is shown that the monomer fluorescence and the excimer fluorescence from a dilute pyrene solution in squalane at room temperature are mainly from "delayed" geminate pairs (Py-, S+) and (Py-, Py+ ), respectively, from the ODESR spectra observed at the monomer and the excimer fluorescence. The reco
