This volume presents solubility data of azides, cyanides, cyanates, and thiocyanates of alkali metals,alkaline earth metals, and ammonium. Covered are binary and ternary systems in all solvents. No solubility data have been found for some of the compounds of alkali metals, alkaline metals, and ammonium. These include beryllium and magnesium azides, lithium,rubidium cesium, ammonium, and alkaline earth cyanates and cyanides, and beryllium thiocyanate. Likewise, no solubility data seem to exist for selenocyanates of the mentioned metals and ammonium. The literature has been covered up to the middle of 2001, and there was a great effort to have the literature survey as complete as possible. The few documents which remained unavailable to the editor, and could not be included in the volume, are listed in the Appendix. For some compounds it was not possible to show the Chemical Abstracts registry numbers since these have not been assigned. For this reason, the registry number index is incomplete.
NIST Recommended Rest Frequencies for Observed Interstellar Molecular Microwave Transitions—2002 Revision33(2004); http://dx.doi.org/10.1063/1.1633275View Description Hide Description
Critically evaluated transition frequencies for the molecular transitions detected in interstellar and circumstellar clouds are presented. The tabulated transitions are recommended for reference in future astronomical observations in the microwave and millimeter wavelength regions. The transition frequencies have been selected through a critical examination and analysis of the laboratory spectral data obtained from the literature. The information tabulated includes the species identity, transition frequency, uncertainty, and quantum state labels. For convenience, representative line antenna temperatures are listed for a typical astronomical source for each transition, and the references are cited for the laboratory and astronomical literature that have been employed.
Revised and Updated Thermochemical Properties of the Gases Mercapto (HS), Disulfur Monoxide Thiazyl (NS), and Thioxophosphino (PS)33(2004); http://dx.doi.org/10.1063/1.1611178View Description Hide Description
Computations were done to correct erroneous data tables given in the 4th edition of the NIST-JANAF Thermochemical Tables. Updated enthalpies of formation were included to compute the thermochemical tables for four ideal gases: mercapto (HS), disulfur monoxide thiazyl (NS), and thioxophosphino (PS).

A new correlation has been developed to represent the second virial coefficient of water as a function of temperature. The formulation was fitted to experimental data, both for the second virial coefficient itself and for a quantity related to its first temperature derivative, at temperatures between approximately 310 and 1170 K. The high-temperature extrapolation behavior was guided by results calculated from a high-quality intermolecular pair potential. The new correlation agrees well with the experimental data deemed to be reliable, and at high temperatures is a significant improvement over the best previous formulation.
Structure and Vibrations of Lanthanide Trihalides: An Assessment of Experimental and Theoretical Data33(2004); http://dx.doi.org/10.1063/1.1595651View Description Hide Description
In the present paper an assessment of experimental and theoretical data on the structure and molecular vibrations of all the lanthanide trihalides is presented. Our review includes 114 references to recent advanced studies. These data facilitated the confirmation of previously suggested trends in the molecular properties of the title compounds and a reliable estimation of the data of less-studied molecules. On the basis of the collected data, a comparative analysis of the experimental and computational results has been performed. This served to assess the capabilities of recent theoretical methods for the above molecular properties.
