✦ Synopsis

Experimental evidence for a strong decrease of intensities in both ligand field and charge transfer spectia with increased metal-ligand distance is presented. It suggests that overlap of charge clouds for metal ion and ligands is a major source of their intensitics. The polarization ratios in noncubic cry stals also appear to be largely determined by differences in bond lengths. Data from the literature are consistent w ith this interpretation. Potential applications of this still tentatise principle for the gathering of structural information on pure and doped erystals as well as on amorphous systems are discussed.
