Abstract Empirical linear combination of atomic orbitals (LCAO) calculations are performed to investigate the electronic structure of Sb2Se3, Sb2Te3, In2Se3 and In2Te3. The bands of bonding p states are overlapped with the bands of lone pair states in these materials. The absorption edges of these materials correspond to indirect gap, and the calculation agrees with experimental values.
