We investigated electron-phonon coupling in phosphorescence from X-traps of a naphthalene crystal at 1.2 K. X-traps were created by doping the crystal with β-halonaphthalenes. The results show that the electron-phonon coupling increases with increasing mass of the heavy atom. In the iodine X-trap, multiphonon structure is detectable. The results are interpreted as a charge-transfer interaction with the adjacent heavy atom.
