The fluctuation of ESR parameters which reflects the intrinsic "site-to-site fluctuation" in glass was extracted by analyzing the ESR lineshape of spin probes, Cu2+ and -induced Cd+, for the wide composition range of soda borate glasses. The results obtained are summarized as follows (i) The lineshape of Cu2+ was closely reproduced by introducing a skewed distribution function of g„into the lineshape function for polycrystalline matters. The skewed distribution of g is consequentially derived from the assumed gaussian distribution function of the ligand field strength. The width of the g-distribution was found to vary with the composition of host glasses and increased in the order; <<, where :Na2O(mol%)13, : 20[Na2O]37, : 55[Na2O] (ii) The hyperfine lineshape of magnetic Cd+ in the glasses was analyzed by assuming tha the shape is completely controlled by the fluctuation of isotropic hyperfine coupling consta . The fluctuation of a was estimated from the apparent line width and its order was found to be The variation of the fluctuation with Na2O content and the difference between the magnitudes of fluctuations measured by Cu2+ and Cd+ were discussed in terms of the bond strength of glass network and around the spin probes.
