A part of cation in polyphosphate was replaced with Mn2+ ion. Zero-field splitting parameter D due to the crystal field with axial symmetry was estimated according to Allen’s method from the ESR spectrum of Mn2+ ion. The value of D changes with the change in the state of polyphosphate, crystalline or glassy. As the degree of polymerization of sodium polyphosphate glass decreases, the value of D increases and approaches to the value corresponding to the crystalline state. These phenomena were interpreted as due to the disorderness of glassy state. The value of D was found to change with the variation of the kind of cation in polyphosphate. This was explained in terms of the effective cationic field.
