Amazon.com description: Product Description: This compendium is an alphabetical listing of terms used in chemistry, with the definitions recommended by various IUPAC commissions dealing with nomenclature and terminology. Terms from physical, inorganic, organic, macromolecular, and analytical chemistry published up to the end of 1985 are included. The book differs from other chemical dictionaries in that the definitions are truly authoritative, being recommendations agreed by committees of experts after consultation with the chemical community; it is intended to be ongoing as some important areas of chemistry have not yet been the subject of IUPAC recommendations and thus is the first step towards a comprehensive and authoritative chemical dictionary.
