The results of a study of the effect of pressure-induced freezing on the energy of the intravalence-transfer (IT) band of the I/sub 3//sup /minus// salt of the mixed-valence diferrocenylacetylene cation are reported. Spectra taken at pressures below and above the freezing point exhibit peak shifts significantly to lower energy but by less than 40% of the predicted value. It is proposed that for intramolecular electron transfer within a large metal complex with pi electrons, the field supplied by the ligands in addition to that of the electrons in the metal-ligand bond plus that of a relatively rigid solvation shell dilutes the effect of the dielectric continuum. 15 references, 1 figure.
