Abstract
The electronic structure of five antimony compounds is investigated and the Sb Mössbauer isomer shift is calculated. Its value obtained from the full band structure calculation gives a quantitative account for the chemical notion of delocalization of the 5s(Sb) lone pair. A simple molecular description is also derived which relates the lone pair to the Sb local environment.
