Abstract : The available molecular parameters, fundamental frequencies, potential barrier heights, torsional frequencies, and standard enthalpies of formation at 298.15 K for selected bromoethanes and iodoethane containing one symmetric-top group have been critically evaluated and recommended values selected. The chemical thermodynamic properties in the ideal gas state at one atmospheric pressure using the rigid-rotor harmonic-oscillator approximation have been calculated for CH3CH2Br, CH3CHBr2, CH3CBr3, C2Br6, and CH3CH2I. The internal rotational contributions have been obtained from the partition function formed by the summation of internal rotation energy levels. (Author)
