Quantities, Units and Symbols in Physical Chemistry Third Edition The first IUPAC Manual of Symbols and Terminology for Physicochemical Quantities and Units (the qGreen Bookq) of which this is a successor, was published in 1969, with the objective of 'securing clarity and precision, and wider agreement in the use of symbols, by chemists in different countries, among physicists, chemists and engineers, and by editors of scientific journals'. Subsequent revisions have taken account of many developments in the field, culminating in the major extension and revision represented by the 1988 edition under the title Quantities, Units and Symbols in Physical Chemistry. This third edition (2007) is a further revision of the material which reflects the experience of the contributors and users with the previous editions. The book has been systematically brought up to date and new sections have been added. It strives to improve the exchange of scientific information between different disciplines in the international pursuit of scientific research. In a rapidly expanding scientific literature where each discipline has a tendency to retreat into its own jargon, this book attempts to provide a compilation of widely used terms and symbols from many sources together with brief understandable definitions and explanations of best practice. Tables of important fundamental constants and conversion factors are included. Precise scientific language encoded by appropriate definitions of quantities, units and symbols is crucial for the international exchange in science and technology, with important consequences for modern industrial economy. This is the definitive guide for scientists, science publishers and organizations working across a multitude of disciplines requiring internationally approved nomenclature in the area of Physical Chemistry.PREFACE The purpose of this manual is to improve the exchange of scientific information among the readers in different ... off course.2 We urge the users of this book always to define explicitly the terms, the units, and the symbols that they use. ... Chapter 10 provides the references, and Chapter 11, the Greek alphabet.
