For more than 90 years, researchers around the world have relied on the CRC Handbook of Chemistry and Physics for authoritative, up-to-date data. This year will be no exception. Many of the most heavily used tables in the book receive major updates and expansions, most notably: Physical Properties of Inorganic Compounds - Features nearly 25% more compounds Enthalpy of Fusion - Contains updated values and 20% more compounds, especially inorganics Bond Dissociation Energies - Includes 70% more compounds, including for the first time more than 1200 molecular ions Table of the Isotopes - Brought up to date with research results through the year 2005 Inorganic Ion and Ligand Nomenclature - Incorporates new rules from IUPAC for systematic names Chemical Carcinogens - Updated in accordance with the recent report from the National Toxicology Program Global Temperature Trends - Traces the rise in mean global temperature for the last 150 years New references will also help keep readers up to date.
