Abstract
The electronic structure and optical properties of praseodymium monopnictides have been investigated. The linear muffintin orbital method in the atomic sphere approximation and the local density approximation to exchange and correlation in density functional theory has been used. The p bands of pnictogen move towards higher energy on going down the pnictogen column. The density of states at the Fermi energy increases on going from PrP to PrSb. The calculated optical conductivity is compared with the available experimental data. The optical conductivity increases with the increase of pnictogen atomic number.
