of anthracene in naphthalenc matrix has been determined by EPR ol the triplet state of the guest molecule. It differs from the host molecule orientation mainly by n rotatio!i of 25" about the : ask.
It is found rhsr these lengths are significantly longer when measurements xc performed on smooth, rather than nonsmooth, nreas of the surface.
Luminescence spectra(4.2 K) and etch patterns of thermally deformed anthraccnc single crystals are investigated. It is shown that the Dt band with AE = 235 cm-t (where AE is the energy gap between the bottom of the exciton band and the DI band) is due to the edge dislocations with the emergences at
The delayed fluorescence (DF), the action DF spectrum, the incident light intensity dependence of the DF and the DF decay of an anthraoene single crystal at 77ยฐK arc analyzed. It is proposed that the delayed fluorescence originates from electron-hole recombinations after photogeneration of charge ca
