PREFACE

The 90th Edition of the CRC Handbook of Chemistry and Physics marks a milestone for this
reference work, which first appeared in 1913. For almost a century the Handbook has been updated
annually, except for a few wartime years, and has served several generations of R&D professionals,
engineers, and students. Its aim has always been to provide broad coverage of all types of physical
science data commonly encountered by scientists and engineers, with as much depth as can be
accommodated in a one-volume format. The data contained in the Handbook have been carefully
selected by experts in each field; quality control is a high priority and the sources are documented.
The annual updates make it possible to add new and improved data in a timely fashion, and
references to more detailed data sources have helped to establish the Handbook as the first place to
look for physical and chemical data.
This edition also marks the retirement of the current Editor-in-Chief after 20 years in that
post. The reception to the changes I have made in the book is very gratifying, and I greatly
appreciate the suggestions that have come from the Editorial Board, the contributors, and many
users. The new Editor will be W. M. “Mickey” Haynes, who has had long experience in providing
physical and chemical data through the National Institute of Standards and Technology and through
his service as Editor of the International Journal of Thermophysics. I am confident that he will
continue the tradition of excellence the Handbook has achieved.
Many new tables and updates are included in the 90th Edition, especially in the following
areas:
Fluid properties (Sec. 6) - new data over a wider temperature and pressure range for
- Water (including D O) and steam
2
- Air
- Refrigerants and other important industrial fluids
Biochemistry (Sec. 7) – new tables on
- Enzyme catalyzed reactions
- Structure and functions of common drugs
- Chemical constituents of human blood
Analytical chemistry (Sec. 8) – new and expanded tables on
- Proton NMR shifts for solvents and other fluids
- Mass spectral peaks
- Nuclear moments and other data for NMR spectroscopy
- Aqueous solubility of organic compounds
Astronomy and geophysics (Sec. 14) – new data on
- Properties of the planets and their satellites
- Major world earthquakes, 850 AD to 2008
- Interstellar molecules
Other new and expanded tables
- International recommendations for the expression of uncertainty of measurements
- Description of the new IUPAC chemical identifier (InChI)
- Nobel prize winners in physics and chemistry
- Threshold limits for airborne contaminants
In addition to offering the full text of the print edition in searchable pdf format, this Internet
Version 2010 presents the major tables of numerical data in the form of interactive tables that can
be sorted, filtered, and combined in various ways. Substances in these tables can be retrieved by
searching on name, formula, CAS Registry Number, or chemical structure, and such a search can be
combined with a request for a desired property. Thus one can request a specific property of a
specific substance (for example, viscosity of benzene) and receive a customized table with exactly
that information. In addition, the Internet version includes a section with pdf files of many older
tables that have been removed from the print edition to make space for new material.
Suggestions on new topics for the Handbook and notification of errors are always
appreciated. Input from users plays a key role in keeping the book up to date. Address all comments

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 assistance and
support of Dr. Fiona Macdonald, Chemical and Biological Sciences Publisher for CRC Press/Taylor
& Francis Books, is greatly appreciated. Finally, I want to thank Mimi Williams, Pam Morrell, Glen
Butler, James Yanchak, and Theresa Delforn for their outstanding work in production of the book
and Ronel Decius, Robert Morris, and Aviel Alkon for producing the Internet version.
