Abstract
The experimental potential energy curves forX 1 3Σ − g ,X 2 3Σ − g ,B 1 3Σ − u ,B 2 3Σ − u ,C 1 3Σ − u andE states of the diatomic selenium molecule have been constructed using the method of Lakshman and Rao and also by Jarmain’s method. The dissociation energy for the ground state of the molecule has been estimated to be 3.31 eV by the method of curve fitting using the electronegativity potential function of Szőke and Baitz. Also the first ionization potential of the Se2 molecule is found to be 8.68 eV.
