Bound and quasilocalized three-particle complexes defect + exciton + fully symmetrical (FS) phonon in the absorption spectra of naphthalene crystals with impurities consisting of heterocyclic compounds in the region of the vibronic transition lA lg —► 1B2uag are observed experimentally and calculated theoretically.
