Determination of the sign of the quadrupole coupling constant of in silicate glasses by Mössbauer spectroscopy

Year: 1997

Type: article

Abstract: High-field Mössbauer spectroscopy was performed on a range of tin-containing ternary and binary silicate glass systems. All the glasses unambiguously exhibited a positive value for for the valence state. Determination of the sign of indicates that the electron distribution around each Sn nucleus is similar at all the tin atoms, which is a significant finding for glasses. These results suggest that the electronic state of the is dictated by its non-bonding electron orbital, which has strong character, and which provides the dominant contribution to the electric field gradient present at the nucleus.
