Abstract
In this study, we present a precise determination of the bond dissociation energy of CO2 using state-to-state resolved threshold fragment yield spectra at a photoexcitation wavelength of around 92 nm. Our findings show that the bond dissociation energy of CO2, CO2 → CO + O, is 43976.12(15) cm-1 or 526.0714(18) kJ/mol. Furthermore, by incorporating our previously measured bond dissociation energies for CO and O2, we determined the dissociation energy of CO2 into C + O2 and the CO2 atomization energy (CO2 → C + O + O) to be 92309.73(21) and 133578.92(18) cm-1 or 1104.2699(25) and 1597.9592(22) kJ/mol, respectively. Thus, the bond dissociation energies of CO2 for all channels now have uncertainties of 0.2 cm-1 or 0.002 kJ/mol. These results serve as reference points for the enthalpies of C atom and CO and CO2 molecules and provide benchmarks for high-level ab initio quantum chemistry calculations.
