The three-body dissociation of I-2(-) (CO2) following excitation of the I-2(-) chromophore to the repulsive A'(2)Pi(g,1/2) and B-2 Sigma(+)(g,1/2) electronic states at 1.72 and 3.21 eV has been investigated using fast beam photofragment translational spectroscopy. The translational energy distributions for three-body dissociation provide a direct measurement of the CO2 binding energy, yielding a value of 218 +/- 10 meV. These distributions are vibrationally resolved and show that some CO2 is produced with bend excitation. Dalitz plots show that the dominant three-body decay mechanism is asynchronous-concerted decay, in which the two bond cleavages are distinct but nearly simultaneous events. (C) 2011 Elsevier B. V.
