Book Review Analytical Methods for Pesticides Plant Growth Regulators and Food Additives (in 4 Vols.). Edited by G. Zweig. Vol

код для вставкиСкачать
“Amino nucleoside” is the designation given t o the basic
nucleoside obtained from the antibiotic puromycin after the
elimination of p-methoxyphenylalanine; in i t , 6-dimethylaminopurine is attached by a glycosidic linkage t o 3-aminoribose. A typical nephrotic syndrome can be produced
experimentally in rats by this amino nucleoside, and the
present article (1 12 pp., 245 references) is intended t o contribute t o an understanding of nephrotic syndromes in
humans.
A subject index for this volume and a n author index and
article index for Vols. 1-7 of the series close the book,
whose outlay and appearance are excellent.

Analytical Methods for Pesticides, Plant Growth Regulators,
and Food Additives (in 4 Vols.). Edited by C. Ziveig.
Vol. I : Principles, Methods, a n d General Applications.
Academic Press, N e w York-London 1963. 1st edit., xiv
637 pp., numerous illustrations and tables, linen $24.00.
T h e current nutritional laws have caused a n ever increasing
demand for reliable methods for routine control of agricultural products a n d foodstuffs for their content of residues of
pesticides, growth regulators, a n d other similar chemicals
which a r e added t o perishable nutritional goods during their
commercial and industrial production a n d handling.
In this first volume of the series, edited by C. Zweig, on the
analyses of such residues, twenty-seven notable American
authors from universities, a n d from industrial a n d government laboratories have combined t o give numerous practical
examples illustrating the methods of formulation analysis, residue analysis, analysis of food additives, extraction and
purification procedures, and toxicological tests. Further
sections a r e allotted t o the fitting-out of laboratories for
residue analysis, t o special procedures, e.g. spectrophotonietry, gas a n d paper chromatography, total halogen analysis, isotopic methods a n d bioassays, to the statistical evaluation of results, and t o special problems of interest in individual branches of food industry.
The forthcoming volumes will contain discussion of the analysis of residues of insecticides (Vol. I I ) , of fungicides, nematicides, soil fumigants, rodenticides, a n d food a n d feed
additives (Vol. III), a n d of herbicides (Vol. 1V). There has
long been a pressing need for a reliable modern laboratory
manual of toxic residue analysis, and hence each of these
volumes will undoubtedly be eagerly awaited and welcomed
by workers in this field.

Chemical Applications of Infrared Spectroscopy. By C. N . R .
Rrro. Acidemic Press, New York-London 1963. 1st edit.,
xiii + 683 pp., numerous illustrations and tables, linen
$19.50.
It is amazing that, with the exception of the world-renowned
book by Belkimy, it has taken so long for monographs o n infrared spectroscopy t o appear in English, although the British
and Americans have had undoubtedly t h e greatest share in
the development a n d application of this subject. For about
two years now a glut of books in English o n this theme has
appeared o n the market; the book by Rrro holds a spezial
position among them. It deals mainly with the chemical a p
plications of infrared spectroscopy. It is onlyin thefirst chapter
that a very brief survey o f the theory of spectra, some experimental influences o n the appearance of spectra, instrumentation and sample preparation, a n d the fundamental applications of infrared spectroscopy a r e given. Chapters 2-7 contain discussions of the spectra of individual classes of compounds. Frequently, despite the brevity of the text, the treatment goes into considerable detail. T h e next three chapters two of them by collaborators - are devoted t o special applications of infrared spectroscopy in organic chemistry and biochemistry and in the field of high polymers. I n conclusion,

there are chapters on quantitative analysis and other subjects
which do n o t fit well into the general scheme of presentation
selected. An appendix is given which includes a short proposal
for a course of instruction in infrared spectroscopy, tables for
band assignments, and commendably extensive author and
subject indexes.
It is only natural t o compare this volume with Belltrmy’s
book. T h e scope of the topics dealt with is the same, a n d the
arrangement of material is largely the same. However, the
presentation in Roo’s book seems t o be more fluent. T h e inclusion of numerous illustrations a n d tables provides a n aid
t o simple comprehension a n d speedy orientation. The abundance of references given for each chapter a r e also collected
together here a n d are more readily surveyed a n d easier t o use.
T h e reviewer does not agree with Rno o n one point, viz. the
divison between the “middle” a n d “far” infrared at 650 cni- 1.
The so-called KBr region at least - because of the techniques
required for measurement therein a n d because of the information it conveys -- a n d perhaps even the whole of the spectral region that can be measured with prism instruments belongs t o the middle infrared, so that the division should be
drawn at 200-250 cm--i.

Behavior of Electrons in Atoms. Structure, Spectra, and
Photochemistry of Atoms. By R. M . Hochstrnsser. T h e
General Chemistry Monograph Series, edited by R. Joliiison. W. A. Benjamin, Inc., New York-Amsterdam 1964,
1st edit., xi + 162 pp.. numerous illustrations, linen $4.50.
paperback $2.15.
T h e electronic theory of the atom forms the basis of all modern instruction in chemistry. It is therefore desirable to
familiarize the student of chemistry as early as possible with
the most important concepts of quantum mechanics. In this
book, R. M. Hochstrnsser attempts t o give a simple presentation of the theory of the a t o m for t h e beginner in chemistry.
T h e author strives t o explain the fundamentals of the theory
without recourse t o the mathematical formalism of quantum
mechanics. T h e starting point for his discussion takes the
form of experimental phenomena which can be easily interpreted.
I n the earlier chapters atomic spectra, the interaction between
atoms a n d electrons (the Franck-Hertz experiment), the wave
nature of particles, the electron shells of atoms, electron spin,
the Pauli principle, a n d the periodic system of the elements
are considered. Finally, the Zeeman effect, interatomic transfer of excitation energy (sensitized fluorescence), a n d the formation a n d properties of excimers a r e discussed. However,
the material covered does include the theory of the chemical
bond.
117 accordance with its purpose, the book is written in a rather
elementary way a n d does not demand any specialized knowledge o n the part of its readers. An understanding of the text
is made quite easy by numerous explanatory diagrams. T h u s
the book seeins ideal for giving the beginner in chemistry a
first impression of the electronic structure of the atom.

The Inorganic Chemistry of Nitrogen. By W . L. Jo//y. The
Physical Inorganic Chemistry Series. Edited by R . A . Plum
a n d M . J. Sienko. W. A. Benjamin, Inc., New YorkAmsterdam 1964. 1st edit., xi + 124 pp., numerous illustrations and tables, linen 55.75.
The present volume in this series is intended t o give a survey
of nitrogen a n d its inorganic compounds with particular emphasis o n their physical and physico-chemical properties.
Following a comparison of nitrogen with the elements carbon
phosphorus, and oxygen, elemental nitrogen as such is discussed, with particular attention t o the nature of the bonding
in the N2 molecule. This is followed by a chapter on ammonia, including the use of liquid NH3 as a medium for reactions,
