код для вставкиСкачать
In the fourth volume of the series “Fluorine Chemistry” [*I,
H. C . Hodge and F. A . Smith deal exclusively with the biological properties of inorganic fluorides (Chapter 1 , 3 6 3 pp.) and
effects of fluorides o n bones and teeth (Chapter 2, 306 pp.).
The acute and chronic toxic properties of fluorine towards
man and animals, the biological properties (reactions with
enzymes), and the metabolism rJf inorganic fluoride are
described in the first chapttr. Doses and effects of fluorides
are summarized in 58 tables.
The second chapter describes the role of fluorine in the
human and aniinal orpanism, and placer special emphasis on
the problem of the Iffevention of tooth decay.
Twenty tables deal with the fluoride content of bones and
teeth the elimination of fluoride, histological changes in
bones and teeth, and clinical investigations with inorganic
The book is richly illustrated with diagrams, and
contains 84 pages with 3780 references. The fourth volume of
“Fluorine Chemistry” should be particularly important as a
reference work.

Computer Programming for Chemists. By K . B. Wiberg.
Frontiers in Chemistry. W. A. Beniamin, Inc.. New YorkAmsterdam 1965. 1st ed., viii, 269 pp., 13 tables, bound
The development of the program languages FORTRAN
(FORmula TRANslation) and ALGOL (ALGOrithmic
Language) has greatly simplified the programming of
electronic computers. These program languages permit the
formulation of a problem without reference to the type of
computer to be used. This presupposes, naturally, that the
computer in question is equipped with a FORTRAN or
ALGOL translation program.
This book is an introduction to programming in FORTRAN.
One chapter also deals with the symbolic internal program
language FAP (Fortran Assembly Program). An introduction to the input and output of data is followed by an explanation of arithmetical expressions, functions, and subprograms. The various “statements” are mostly illustrated by
examples, so that their general significance at first remains
rather in the background; however The most important
statements are again summarized in a special chapter and
their operation explained. Nearly every chapter contains
exercises for practice, the solutions of which are given in the
appendix. Many prograrnsaome of them very comprehensive,
from the fields of kinetics, N M R spfctroscopy, and quantum
chemistry are given in a special chapter These add greatly to
the value of the book, since, as photoreproductions of tested
programs they are free from errors and offer the reader the
opportunity to analyse and understand the programs of
others. The author sees this as “the best method of becoming
familiar with computer programming”, and the reviewer
must agree with this view. In order to understand definitions
of FORTRAN statements and FAP instructions that lie
beyond the scope of the book, many readers will still refer
to the existing literature, but K . B. Wiberg’s book will prove
a great help to both the beginner and the initiate in the
construction of serviceable programs.

Melting and Crystal Structure. By A . R . Ubbelohde Clarendon
P r e s Oxford 1965. 1st ed., xi, 320 pp., several illustrations
and tables, paper E3.3.0.
Despite many experimental and theoretical studies on the
liquid and crystalline states of matter, the process of melting
still presents a host of problems in connection with both the
equilibrium and the kinetics of the process. For this reason

Edit. 4, 613 (1965).
even the specialist will welcome the publication of Ubbelohde’s
book, which contains an excellent discussion of melting
from the viewpoints of thermodynamics and of atomic
Starting with the phenomenological observations on melting,
with special reference to modern findings on behavior under
high pressures, a short description of the more traditional
ideas of Lindemann and others is followed by a systematic
discussion of the influence of special structural properties and
of cooperative phenomena up to the Lennard-Jones and
Devonshire theory of melting for simple crystals, and its
modification for the superposition of several melting mechanisms in more complicated cases. Individual chapters deal
with pure crystal lattice transitions (which are related to
melting) and the melting of glasses, liqyrd crystals, and polymeric materials; premelting and precrystallization in the
liquid phase and the rates of melting and of nucleation are
discussed in detail. Tnese di5cussions are based o n extensive
experimental material, which is presented to the reader in
the form of numerous tables showing the influence of the
various parameters.
A book on a subject that is very much a center of interest is
naturally stamped with the autnor’s personal views, so that
one or other idea or special theory receives little or n o
attention (this is true e.g. of the Kirkwood-Monroe theory) ;
in every case, however, the reader finds a detailed discussion
of fundamentally similar ideas, the author probably having
given preference to points that demand less theoretical
knowledge on the part of the reader, and this should gain the
book a wide circle of users.

Nonexistent Compounds - Compounds of Low Stability. By
W.E.Dasent. Marcel Dekker. Inc.. New York1965.lst ed.,
ix, 192 pp., several illustrations, bound, S 8.50.
At a time when new types of compounds whose existence
formerly was deemed impossible are being discovered with
ever-increasing frequency, the title “Nonexistent Compounds’’ is as attractive as it is daring. For good reason the
author himself adds the neutralizing subtitle “Comqxmds
of Low Stability”.
There is scarcely a preparative chemist who has not had the
experience of finding that one or other of the compounds he
wishes to prepare is unobtainable in spite of all his efforts.
Moreover, lecturers at universities are only too familiar
with the penetrating questions of students regarding the
“gaps” in the otherwise rigid taxonomy of chemistry. For
these reasons Dasent’s book, which was preceded a few
years earlier by an article by the same author [Journal of
Chemical Education 40, 130 !963)], can wpect a good
However, this small volume can, of necessity, only partly
satisfy o m expedations, although the author discusses a
number of interesting examples in such a way that similar
problems can also be worked out on this basis. A list of
407 references is particularly valuable in this respect. In view
of the examples chosen, this book may be recommended in
particular to the inorganic chemist.
