Luminescence and absorption spectra of coronene single crystals are studied. Freeexciton luminescence is observed for the first time. The intensity of free-excitonluminescence decreases with decreasing temperature, suggesting that free excitons arein thermal equilibrium with excitons in a relaxed state which is located 1070 cmbelow the bottom of the free-exciton band. The line shape of the 0-0 absorptionband which is located at 23220 cm at 10.4 K is Lorentzian, indicating that scatteringof excitons by phonons is weak.coronene single crystal, free-exciton luminescence, scattering of exciton
