The optical-optical double resonance method has been used to excite selected vibrational levels of the E(0(+)) and f(0(+)) ion-pair states of ClF. Subsequent bound-free transitions terminating on three repulsive valence states, Y((3)Sigma(0+)(-)), B-1(3II(0+)), and C((1)Sigma(0+)(+)), have been analyzed. The-bound-free continua have been modeled to obtain analytical expressions for the three 0+ repulsive potentials and to improve the description for the E(0(+)) and f(0(+)) state potentials. One of the repulsive states is Y((3)Sigma(0+)(-)), which is responsible for the predissociation of B((II0+)-I-3). The transition dipole functions also have been assigned for the bound-free transitions. The molecular orbital configurations of the lower states are discussed. Finally, the influence of homogeneous interaction between the E(0(+)) and f(0(+)) states on the bound-free spectra from certain vibrational levels: is discussed.
