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
Triplet energy transfer to a guest in a pyrene host matrix is used to lomate the triplet excimer level in solid pyrenc. Tbe fohtion is found to be between 15 800 cm-' and 16 506 cml. A mixed triplet excimer from pyrene-1,12benzperyhe
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
