A new estimate is derived for the group additivity contribution ΔH ƒ∘[O—(O)2] = 55 ± 6 kJ mol−1, based upon recent experimental data, which enables heats of formation and bond dissociation energies to be estimated for species ROnR and RO n¨(R = H, CH3, and CF3). Semi‐empirical MNDO calculated heats of formation, for these species, provide independent support for the new thermochemical estimates. The results are also consistent with other theoretical and experimental evidence.
