Binding
Energies in Atomic Negative Ions: III
T. Andersen,
H. K. Haugen, and H. Hotop
This article updates
a fourteen-year-old review on this subject [J. Phys. Chem. Ref. Data
14, 731 (1985)]. A survey of the electron affinity determinations
for the elements up to Z = 94 is presented, and based upon these
data, a set of recommended electron affinities is established. New developments
in the experimental methods which yield accurate electron binding energies
are described. Fine structure splittings and excited state energies
of negative ions as well as lifetimes of metastable states are given.
Progress in theoretical calculations of atomic electron affinities is
documented by comparison with reliable experimental data.
Estimating
Solid-Liquid Phase Change Enthalpies and Entropies
James S. Chickos, William E. Acree, Jr., and
Joel F. Liebman
A group additivity method based on molecular
structure is described that can be used to estimate solid-liquid total
phase change entropy and enthalpy of organic molecules. The estimation of these phase changes is described, and examples
are provided to guide the user in evaluating these properties for a
broad range of organic structures.
A total of 1858 compounds were used in deriving the group values,
and these values are tested on databases of 260 additional compounds
(399 references).

III. Review of Previous Thermodynamic Property Values for Chromium and
Some of its Compounds
Duane R. Kirklin
Twenty-eight crystalline
and aqueous chromium species from the NBS Tables of Chemical Thermodynamic
Properties were selected based upon their possible importance to environmental
fate and remediation processes. Their NBS files were studied to determine
the sources of information and the methodology used to determine the
NBS selected thermodynamic values. The NBS Tables for chromium were
compiled in 1966. A literature search was performed to determine the
existence of additional data for these species.
Revised
Thermochemical Properties of Phosphinidene (PH), Phosphine (PH3),
Phosphorus Nitride (PN), and Magnesium Phosphate (Mg3P2O8)
Katharina Lodders
Revised Thermochemical
Tables for phosphinidene (PH), phosphine (PH3), phosphorus
nitride (PN), and magnesium ortho-phosphate (Mg3P2O8)
are computed. These computations were done because the P reference state
was not adjusted to the white P reference state and/or because the tables
of these compounds are printed erroneously in the 4th edition of the
NIST-JANAF Thermochemical Tables
CODATA
Recommended Values of the Fundamental Physical Constants: 1998
Peter J. Mohr
and Barry N. Taylor
This paper gives
the 1998 self-consistent set of values of the basic constants and conversion
factors of physics and chemistry recommended by the Committee on Data
for Science and Technology (CODATA) for international use. Further,
it describes in detail the adjustment of the values of the subset of
constants on which the complete 1998 set of recommended values is based.
The 1998 set replaces its immediate predecessor recommended by CODATA
in 1986. The new adjustment, which takes into account all of the data
available through 31 December 1998, is a significant advance over its
1986 counterpart. The new set of recommended values is available on
the World Wide Web at http://physics.nist.gov/constants.

Phase
Diagrams and Thermodynamic Properties of Binary Systems of Drugs ....
p.889
James Sangster
The phase diagram
data of 60 binary systems of drugs were evaluated with the aid of a
computer-coupled phase diagram/thermodynamic analysis. Data for this
analysis were obtained by an exhaustive literature search (110 references).
Among the results of this analysis are the excess Gibbs energy of liquid
and solid solution phases, and the thermodynamic properties of intermediate
compounds. For each system, a phase diagram was calculated; such calculated
diagrams are thermodynamically consistent and are offered as the best
constructions which can be deduced from available data.

Solubility Data Series 69. Ternary Alcohol-Hydrocarbon-Water System
.... p.983
Adam Skrzecz,
David Shaw, and Andrzej Maczynski
The mutual solubilities
of ternary systems containing alcohols, hydrocarbons, and water are
reviewed. An exhaustive search of the literature was attempted for numerical
data on all alcohols and hydrocarbons which are liquid at STP. Data
were found for alcohols with up to nine carbon atoms, but mostly with
fewer than four carbons. Data were found for a variety of hydrocarbon
structural types including alkane, alkene, and arene. A total of 205
original studies treating 116 ternary systems which have been published
through 1992 are compiled. For 47 systems, sufficient data were available
to allow critical evaluation. All solubility data are expressed as mass
and mole fractions as well as the originally reported units. Similar
reviews of the related binary systems have previously been prepared
for the Solubility Data Series.

Ch. Tegeler,
R. Span, and W. Wagner
This work reviews
the available data on thermodynamic properties of argon and presents
a new equation of state in the form of a fundamental equation explicit
in the Helmholtz energy. The functional form of the residual part of
the Helmholtz energy was developed by using state-of-the art linear
optimization strategies and a new nonlinear regression analysis. The
new equation of state contains 41 coefficients, which were fitted to
selected data of the following properties: (a) thermal properties of
the single phase (p T) and (b) of the liquid-vapor saturation curve
(ps, ', ") including the Maxwell criterion, (c) speed of sound w, isochoric
heat capacity cv, second and third thermal virial coefficients B and
C, and second acoustic virial coefficient Ba. Independent equations
for the vapor pressure, for the pressure on the sublimation and melting
curve, and for the saturated liquid and saturated vapor densities are
also included.

properties of the KCl+H2O system were obtained from previously published
measurements for this system.
Evaluation
of Calculated and Measured Electron Inelastic Mean Free Paths Near Solid
Surfaces .... p.19
C. J. Powell
and A. Jablonski
An analysis is
given of the consistency of calculated and measured electron inelastic
mean free paths (IMFPs) near solid surfaces for electron energies between
50 eV and 104 eV, the energy range of relevance for surface analysis
by Auger-electron spectroscopy and x-ray photoelectron spectroscopy.
This evaluation is based on IMFPs calculated from experimental optical
data and on IMFPs measured by elastic-peak electron spectroscopy (EPES).
We describe methods used for the calculations and measurements, and
we identify the various sources of uncertainty.

M.W. Chase,
Jr.,
Recommended temperature-dependent
values are provided for chemical thermodynamic properties of inorganic
substances and for organic substances containing only one or two carbon
atoms. These tables cover the thermodynamic properties over a wide temperature
range with single-phase and multiphase tables for the crystal, liquid,
and ideal gas state. The properties tabulated are heat capacity, enthalpy,
entropy, Gibbs energy function, enthalpy of formation, Gibbs energy
of formation, and the logarithm of the equilibrium constant for formation
of each compound from the elements in their standard reference states.
All values are given in SI units and are for a standard-state pressure
of 100 000 Pa (1 bar). Each tabulation is accompanied by a critical
evaluation of the literature upon which the thermochemical table is
based. Literature references are given. This volume is an update to
the Third Edition which was published in J. Phys. Chem. Ref. Data,
Volume 14 Supplement 1 (1985). It contains new and revised tabulations,
In addition, it contains numerous corrections to errors (both typographical
and numerical) which resulted from the massive changes made for the
Third Edition.
