Enthalpies of formation of acetyl radicals
Russian Journal of Physical Chemistry A, 2013The database on the enthalpies of formation (Δf H ○) of aliphatic acetyl radicals of the RC·(O) type is analyzed and extended. Δf H ○ values are estimated for the first time for three compounds on the basis of experimental data. The data were analyzed using the additive group approach with

Enthalpy of formation of thiophene derivatives
Chemistry of Heterocyclic Compounds, 2011The enthalpy of formation in the gas phase has been calculated for 21 carbonyl compounds of the thiophene series with the aid of the PM3, MINDO, AM1, and MNDO semiempirical quantum-chemical methods. Comparison of them with experimental data showed that the best linear correlation was achieved with the PM3 method.

Enthalpy of formation of uranium sesquicarbide
The Journal of Chemical Thermodynamics, 1969Abstract The enthalpy of formation of uranium sesquicarbide has been determined by means of oxygen bomb calorimetry and found to be ΔH f o (U 2 C 3 , 298.15 K) = −(43.4 ± 1.8) kcal mol −1 .

Enthalpies of formation of alkyl radicals
Russian Chemical Bulletin, 2014The data on the enthalpies of formation (Δf H°) for alkyl radicals (R·) were examined. Taking into account the values of enthalpies of C-X bond dissociation (X = H, Cl) in alkanes and their monochlorosubstituted derivatives, Δf H° of fifteen R· were determined for the first time.

Enthalpy of formation of europium monoxide
The Journal of Chemical Thermodynamics, 1969Abstract The enthalpy of formation of europium monoxide (EuO1.02) has been determined by means of oxygen bomb calorimetry and found to be ΔHfo(298.15 K, EuO1.02) = − (143.3 ± 0.5) kcal mol−1. A value of ΔHfo(298.15 K, EuO) = − (135.0 ± 1.3) kcal mol−1 was derived.

Enthalpy of formation of europium sesquioxide
The Journal of Chemical Thermodynamics, 1972Abstract An oxygen bomb calorimeter and a solution calorimeter have been used to confirm the value for the enthalpy of formation of europium sesquioxide. The value obtained from the former was ΔH f o (Eu 2 O 3 , mono., 298.15 K) = − (394.6 ± 0.9) kcal th mol −1 and from the latter, ΔH f o = −(394.8 ± 1.5) kcal th mol −1 , to give a weighted
