Description: Energy levels, with classifications and uncertainties, have been compiled for the spectra
of the neutral atom and all positive ions of sodium (Z=11). Wavelengths with classifications,
intensities, and transition probabilities are also tabulated. In addition, ground
states and ionization energies are listed. Where available, the hyperfine structure constants
and the percentages of the leading components of the energy levels are included.
For all ionization st...
Description: This volume presents solubility data for rare earth metal chlorides in water and in
ternary and quaternary aqueous systems. The material is divided into three parts: scandium
group (Sc, Y, La )light lanthanide (Ce-Eu), and heavy lanthanide (Gd-Lu) chlorides;
this part covers the scandium group. Compilations of all available experimental
data are introduced for each rare earth metal chloride with a corresponding critical evaluation.
Every such evaluation cont...
Description: Experimental thermochemical properties of benzene, toluene, and 63 polycyclic aromatic
hydrocarbons, published within the period 1878–2008 (over 350 references), are
reported. Available experimental data for the enthalpies of combustion used to calculate
enthalpies of formation in the condensed state, combined with sublimation, vaporization,
and fusion enthalpies, are critically evaluated. Whenever possible, recommended values
for these thermochemical proper...
Description: Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are of global concern due to their persistence, their tendency to bioaccumulate, and their extremely high toxicity. The fate of the PCDD/Fs in the environment is largely determined by their physical-chemical properties, such as solubility in water (SW, mol m−3), solubility in octanol (SO, mol m−3), and vapor pressure (P, Pa). It is not unusual that the range of reported value...
