✦ Synopsis

The fluorescence and excitation spectra of trans dlmer of acenaphthylene ma Shpol'skn matnx at 4K are reported The spectra at 4K are compared with the fluorescence and excltatlon spectra at 77K, previously reported by us A reassignment of the ongm of the two electronic states 1s required by such a comparison The comparison once again estabhshes the point that the g state IS below the u state, as was ongmally found from the comparison of two-photon and one-photon spectra However, the sphttmg, which was orlgmally described as "exclton sphttmg" should actually be ascribed to "site sphttmg" The "exclton sphttmg", as gwen m the present study, 1s about 130 cm-'
