On the Dissociation Energy of O2 and the Energy of the O2+ b 4Sigmag- State
|Cosby 1992 gives a good analysis of all the data available on the dissociation energy of O2. They also comment that there is a discrepancy between the term values of Lewis 1985 and Gibson 1991 of up to 0.7 cm-1, as well as a discrepancy between spectroscopic and positive ion cycle results.
