From observations and ana!ysis of the pyrene crystal excimer fluorescence spectra from 4OK to 353OK, the cxcimer interaction potcntinl V' = 51 33U-(1.136~ 106)/d (cm-l) has been determined as a function of the intermolecular separation Y iA). V is consistent with an exciton resonance state originati
The absorption spectrum of the pyrene excimer in a single crystal has been measured. The spectrum is similar to that obtained in solution. The polarization of the absorption peaks in the crystal was found to be similar to that of the excimer fluorescence emission. The overlap between the excimeric e
## Abstract Phosphorescence, fluorescence, delayed fluorescence, excimer fluorescence, and delayed excimer fluorescence of pyrene are studied in the host pβterphenyl system. The delayed fluorescence and delayed excimer fluorescence are biexcitonic and exhibit a similar dependency of the emission in
