Tables for Elemental Analysis. Reinhard Krzikalla. xxxv + 294 pages. Verlag Chemie, GmbH, D-6940 Weinheim/Berstr., Postfach 129/149, W. Germany. 1968. DM 28
The present work is a second en larged and revised edition of the collec tion of tables published in 1956 under the title "Rechentafeln zur Chemischen Elementaranalyse." The tables have been completely recalculated from the 1961 International Atomic Weights, which are based on 12 C = exactly 12. They are intended to simplify the cal culation of the percentage composition of a compound from a given formula, or the calculation of the empirical or molecular formula of a compound of known composition. The elements and functional groups included in the tables, and the molecular weights (up to 1000) and numbers of atoms tabulated, have been chosen to meet all practical re quirements. Some elements and func tional groups are now included for the first time. The elements and groups that are not included can be dealt with as residual percentages, or the per centages of functional groups can be found by summing the percentages of their component elements. All instruc tions are given in French and English as well as German.
Mossbauer Effect Methodology. Vol. 5. Irwin J. Gruverman, Editor, viii + 278 pages. Plenum Publishing Corp., 114 Fifth Ave., New York, Ν. Υ. 10011. 1970. $19.50
This fifth volume of a series records the proceedings of the Fifth Symposium on Mossbauer Effect Methodology which was centered on the themes of spectroscopy, new applications, and methodology. Fourteen papers are presented. Environmental control with a He 3 /He 4 refrigerator and techniques for measurements in radioactive ma terials were of particular interest. Man}· of the papers report work in areas remote from pure physics, and include metallurgical, mineralogical, and biological applications. There is a complete subject index at the end of the book.
