Spectra of divalent transition metal ions in ZnCl 2 , KOAc‐Ca(OAc) 2 , KNO 3 ‐Ca(NO 3 ) 2 , and K 2 SO 4 ‐ZnSO 4 glasses are presented. Ions with low octahedral site preference energies (e.g. CO 2+ ) can be used as “probes” for divalent cations in glass and can indicate the presence or absence of network structures. Thus ZnCl 2 glass has a tetrahedral network structure, analogous to vitreous BeF 2 , but KOAc‐Ca(OAc) 2 and KNO 3 ‐Ca(NO 3 ) 2 glasses contain potassium ions and discrete acetatocalcate(II) and nitratocalcate(II) “complex ions.” The structure of acetate and nitrate glasses is discussed in terms of the ideal glass concept.
