Atomic and Molecular Physics


The dissociation energies of the diatomic molecules GaF, InF and TlF have been computed by fitting empirical potential functions to the true potential energy curves for the electronic ground states of the molecules. The five parameter Hulburt-Hirschfelder function and Rao and Reddy's modified potential function have been used. The estimated dissociation energies are 9.772±0.288, 8.571±0.256 and 7.209±0.641 kJ/mol for GaF, InF and TlF, respectively. These values are in good agreement with literature values. The first ionization potentials for these molecules are estimated.
