The bond dissociation energies of Ti[sup +][sub 2], V[sup +][sub 2], Co[sup +][sub 2], and Co[sup +][sub 3] have been measured from the sudden onset of predissociation in the photodissociation spectra of these molecules, yielding values of [ital D][sup [circ]][sub 0](Ti[sup +][sub 2])=2.435[plus minus]0.002 eV, [ital D][sup [circ]][sub 0](V[sup +][sub 2])=3.140[plus minus]0.002 eV, [ital D][sup [circ]][sub 0](Co[sup +][sub 2])=2.765[plus minus]0.001 eV, and [ital D][sup [circ]][sub 0](Co[sup +][sub 3])=2.086[plus minus]0.002 eV. These values are in good agreement with values previously determined from collision-induced dissociation experiments. General criteria for the interpretation of predissociation thresholds as bond dissociation energies and periodic trends in the bonding of the 3[ital d] transition metal diatomic neutrals and monocations are discussed.
