Show Abstract
A compendium of phase change enthalpies published within the period 1880–2010 is reported. Phase change enthalpies including fusion, vaporization, and sublimation are included for organic, organometallic, and a few inorganic compounds. This compendium is a combination of three previous series focusing on phase change enthalpies updated to 2009. Sufficient data are presently available for some compounds to permit thermodynamic cycles to be constructed, an important manner of evaluating the reliability of the measurements. Temperature adjustments of phase change enthalpies from the temperature of measurement to the standard reference temperature, T = 298.15 K, are briefly disscussed and a protocol for doing so is illustrated.

The Thermodynamic Properties of the f-Elements and Their Compounds. I. The Lanthanide and Actinide Metals

Rudy J. M. Konings and Ondrej Beneš

Show Abstract
A critical review of the thermodynamic properties of the lanthanide and actinide elements is presented. The available literature data for the solid, liquid, and gaseous state have been collected and recommended values are presented. In case experimental data are missing, estimates have been made based on the trends in the two series.

Wavelengths, Transition Probabilities, and Energy Levels for the Spectra of Barium (Ba III through Ba LVI)

J. E. Sansonetti and J. J. Curry

J. Phys. Chem. Ref. Data 39, 043103 (2010); http://dx.doi.org/10.1063/1.3432516 (99 pages)

Show Abstract
Energy levels, with designations and uncertainties, have been compiled for the spectra of barium (Z = 56) ions from doubly ionized to hydrogenlike. Wavelengths with classifications, intensities, and transition probabilities are also tabulated. In addition, ground states and ionization energies are listed. For many ionization stages experimental data are available; however, for those for which only theoretical calculations or fitted values exist, these are reported. There are a few ionization stages for which only a calculated ionization potential is available.
