PREFACE

The 84th Edition of the CRC Handbook of Chemistry and Physics features a completely new
version of the most heavily used table, Physical Constants of Organic Compounds. This is the
first revision of the table since 1994. Compounds have been selected for inclusion in the new
table by a careful screening of lists of organic compounds that are important in laboratory
research, industrial chemistry, environmental protection, drug development, teaching, and other
active areas. In this way priorities were established for choosing the most significant compounds
out of the millions of organic substances that have been reported in the literature. Property data
for the selected compounds have been updated, and new structure diagrams, which show much
more detail than the previous structures, have been drawn for all the compounds.

This Internet version of the 84th Edition has added 17 new subsections that can be accessed as
interactive tables. These include tables on Heat of Combustion, Activity Coefficients,
Refrigerants, Amino Acids, Chemical Carcinogens, Laboratory Solvents, and other topics. The
search screens have been modified to make them more user friendly, and there is now a subject
index that permits boolean searching on the name of a physical property and the identifiers of a
chemical substance (name, formula, or CAS Registry Number). An option has been added to the
table displays that permits locking the left-most column, which usually contains the chemical
name, when scanning a wide table. Tool-tips that explain the data in a column now appear when
the cursor is held over that column heading, and it is now possible to export the results of a search
directly into an Excel file.

Other new features of the 84th Edition include:
• An update and expansion of the table of Critical Constants of Fluids, with many new
compounds and recently published data
• A new version of Properties of Refrigerants, which covers fluids now used in
refrigeration systems and those being considered as substitutes
• A new table on Fermi Energy and Related Properties of Metals
• New tables of practical laboratory data such as Flame and Bead tests, Flame
Temperatures, and Density of Ethanol-Water Mixtures
• An update of lists of Chemical Carcinogens and Interstellar Molecules.

The Handbook of Chemistry and Physics is dependent on the efforts of many contributors
throughout the world. The list of current contributors follows this Preface. The new table of
Physical Constants of Organic Compounds could not have been completed without the help of
Dr. Fiona Macdonald, who oversaw the structure drawing and checked names and formulas.
Thanks are also due to Janice Shackleton, Trupti Desai, Nazila Kamaly, Matt Griffiths, and
Lawrence Braschi, who participated in drawing the structures.

FUNDAMENTAL PHYSICAL CONSTANTS

Peter J. Mohr and Barry N. Taylor

These tables give 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. The 1998 set replaces the previous set of constants recommended by CODATA in 1986; assigned

uncertainties have been reduced by a factor of 1/5 to 1/12 (and sometimes even greater) relative to the 1986

uncertainties. The recommended set is based on a least-squares adjustment involving all of the relevant experimental

and theoretical data available through December 31, 1998. Full details of the input data and the adjustment

procedure are given in Reference 1.

The 1998 adjustment was carried out by P. J. Mohr and B. N. Taylor of the National Institute of Standards
an d Technology (NIST) under the auspices of the CODATA Task Group on Fundamental Constants. The Task
Gr oup was established in 1969 with the aim of periodically providing the scientific and technological communities
wi th a self-consistent set of internationally recommended values of the fundamental physical constants based on all
app licable information available at a given point in time. The first set was published in 1973 and was followed by a
rev ised set first published in 1986; the current 1998 set first appeared in 1999. In the future, the CODATA Task
Gr oup plans to take advantage of the high level of automation developed for the current set in order to issue a new
set of recommended values at least every four years.

At the time of completion of the 1998 adjustment, the membership of the Task Group was as follows:

F. Cabiati, Istituto Elettrotecnico Nazionale “Galileo Ferraris,” Italy

E. R. Cohen, Science Center, Rockwell International (retired), United States of America
