Tables of Physical Properties and Constants

Finally, two sets of physical properties have been correlated by the Hammett equation. Sharpe and Walker have shown that changes in dipole moment are approximately linearly correlated with ct-values, and Snyder has recently correlated the free energies of adsorption of a series of substituted pyridines with u-values. All the reaction constants for the series discussed are summarized in Table V. 

G. W. C. Kaye and T. H. Laby, Tables of Physical and Chemical Constants, Longman 1995, gives a table of properties of the nuclides including isotopic abundance or half-life, decay modes, mass excess, neutron capture cross-section and ground-state spin and parity. This publication, with a prospect of regular updates, is available on the website http //www.kayelaby.npl.co.uk/. 

An overview ofthe properties ofthe materials we are studying is presented in Table 18.11. The objective of this work was to find new approaches to the problem of generating new media with low dielectric constants and high thermal stabilities for use as interlayer dielectrics in microelectronic interconnection applications. We have been partially successful in this quest but there is still much more work to be done. The materials we have been able to deposit remain to be characterized in frill detail, which includes not only elucidating their molecular structure but also measuring the panoply of physical properties necessary for practical applications. 

Other important handbooks include Chemical Properties Handbook (Yaws 1999) and the CRC Handbook of Chemistry and Physics (Weast and Tide 1989) Tables of Physical and Chemical Constants (Kaye and Laby 1986) is a more compact handbook of physical and chemical data. One should be on guard that sometimes, when experimental results are not available, the editors may list estimated values in a handbook, which are of less certain accuracy. A printed handbook normally has only limited reverse search capability, of going from a set of properties to the structures that have these properties. 

Ideal-gas tables of thermodynamic properties derived from statistical mechanics are based on the thermodynamic temperatures (as well as on the values of the physical constants used) and are hence independent of any practical temperature scale. The enthalpy of formation, Gibbs energy of formation, and logarithm of the equilibrium constant might depend on temperature-adjusted data.
