Luminescence and absorption spectra under hydrostatic pressures in the range 0-50 kbar have been studied. The instability of free excitons occurs in tetracene, anthracene and phenanthrene crystals, while the instability of self-trapped excitons occurs in α-perylene and pyrene crystals. Experimental results lead to a conclusion that the exciton-phonon coupling constants in those materials are well expressed as a function of the intermolecular distance between nearest-neighbor, plane-parallel molecules.
