The limited electron collision cross-section and transport-coefficient data for the plasma processing gas perfluorocyclobutane are synthesized, assessed, and discussed. These include cross sections for total electron scattering, differential elastic electron scattering, partial and total ionization,dissociation into neutral fragments, and electron attachment, as well as data on electron transport,ionization, and attachment coefficients. The available data on both the electron collision cross sections and the electron transport coefficients require confirmation. Also, measurements are needed of the momentum transfer and elastic integral cross sections, and of the cross sections for other significant low-energy electron collision processes such as vibrational and electronic excitation. In addition, electron transport data over a wider range of values of the density-reduced electric field are needed. The present assessment of data on electron affinity, attachment, and scattering suggests the existence of negative ion states near 4.9, 6.9, 9.0, and 10.5 eV.

The structural,spectroscopic, and thermodynamic properties of 10 gas phase organic molecules related to atmospheric chemistry, including three peroxides and four carboxylic acids, are reviewed. The calculation of the thermochemical tables involved the critical evaluation of new spectroscopic data, enthalpy of formation determinations, and the use of recent internal rotation data. Since insufficient information to characterize all 10 molecules exists, estimation schemes were used to provide the missing experimental and theoretical data.
Equations of State for Cu, Ag, and Au for Wide Ranges in Temperature and Pressure up to 500 GPa and Above30(2001); http://dx.doi.org/10.1063/1.1370170View Description Hide Description
New constraints on the volume dependence of the Grüneisen parameter are derived from a comparison of earlier shock wave data with more recent ultrasonic data for the bulk modulus and its pressure derivative in the frame of a rigorous Mie–Grüneisen model. This model uses a specially “Modified pseudo-Debye–Einstein model” for an accurate representation of the thermal energy and pressure. Within this framework, previous discrepancies between shock wave and static data concerning the equations of state for various reference materials (like Cu, Ag, and Au) are resolved, the corresponding pressure scale is refined, and the uncertainties in this scale are estimated.

This volume presents solubility data of the carbonates, salts of carboxylic acids, and other carbon containing compounds of actinides. Covered are compounds of thorium, uranium, neptunium, plutonium, americium, and one system for curium. No solubility data on carbonates or other carbon containing compounds have been found for other actinide elements. The literature has been covered up to the end of 1999, and there was a great effort to have the literature survey as complete as possible. Only those published results that report meaningful data were considered for the volume. Papers that reported qualitative results with statements like “sparingly soluble” or “insoluble,” etc. were not considered. In addition to papers that published numerical data, some papers that presented data in graphical form only were considered as well. They were considered for the volume either if no other data were available for the system, if the data were published in difficult to obtain older literature, or if the data were considered to be of importance for other reasons. For many compounds it was not possible to provide the Chemical Abstracts Registry Numbers since these have not yet been assigned. For this reason, the Registry Number index is incomplete.
