Phase Transition Enthalpy Measurementsof Organic and Organometallic Compounds. Sublimation, Vaporizationand Fusion Enthalpies From 1880 to 201039(2010); http://dx.doi.org/10.1063/1.3309507View Description Hide Description
A compendium of phase change enthalpies published within the period1880–2010 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 ofthree previous series focusing on phase change enthalpies updatedto 2009. Sufficient data are presently available for some compoundsto permit thermodynamic cycles to be constructed, an important mannerof evaluating the reliability of the measurements. Temperature adjustmentsof phase change enthalpies from the temperature of measurement tothe standard reference temperature, , are briefly discussed anda protocol for doing so is illustrated.
The Thermodynamic Properties of the -Elements and Their Compounds. I. The Lanthanide and Actinide Metals39(2010); http://dx.doi.org/10.1063/1.3474238View Description Hide Description
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.

Energy levels, with designations and uncertainties, have been compiled for the spectra of barium 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.
