This book is a second (revised and
extended) edition of a book that began
as the transcripts from a lecture course
given by one of the authors. The focus
is on the physics of one-dimensional
electronic organic materials and on a
brief survey of some applications. The
writing style, which is punctuated with
cartoons and simple sketches, appears
to be intended to make the book less
intimidating to a newcomer to the
field. Descriptions are given in an intuitive fashion with the minimum of mathematical formalism. There are places
where I found this very non-mathematical context to be illuminating, and the
authors present some topics in an innovative and simplified fashion.
One problem with this book is that it
is not clearly targeted towards a reader
with a particular level of understanding.
In some places the authors strive for a
general simplified discussion of concepts
and topics that appears to be directed to
the nonspecialist who only has a very
basic background in physics. However,
in an apparently random fashion, the
authors insert into the discussion language and concepts that can only be
understood by someone with an
advanced knowledge. The neophyte
Angew. Chem. Int. Ed. 2005, 44, 2473 – 2474
interested in learning about the field of
one-dimensional metals will find useful
nuggets of insight, but even more questions, unless he/she has a reasonable
(or in some cases advanced) understanding of solid-state physics. Alternatively,
a well-versed student will find some of
the explanations unique and clever, but
the book falls far short of being a reference source for in-depth discussions of
complex concepts or published works.
Equations are few and far between,
and while the tone of the text generally
presents topics in an authoritative way,
there is no attempt at a rigorous treatment. The authors acknowledge these
issues in the preface, when they suggest
that many readers will need to consult
other resources; however, one must
question the effectiveness of such an
approach.
The book has been extended from
the first edition, and recent topics such
as light-emitting devices, field-effect
transistors, and carbon nanotubes
receive the bulk of the attention. Other
key applications, including actuators,
sensors, and electrochromics are only
given a paragraph without apparent perspective or appreciation of the issues. In
this regard the authors fall short of
directing the interested reader.
The cause of my biggest disappointment with the book is the many chemical inaccuracies. An astute reader will
notice at a glance that the nitrogen
atoms of polypyrrole on the books
cover are shown to be tetrahedral.
Given the importance of the p character
of the nitrogen lone pairs in determining
the properties, one would expect that
the authors would have paid greater
attention to this detail. A significant
fraction of the chemical figures have
errors, and there are multiple instances
of three bonds to carbon, five bonds to
carbon, or two bonds to nitrogen, and
places where radicals or charges are
positioned on structures indiscriminately or incorrectly. Shish-kebab metallophthalocyanines are drawn with what
looks like Cl22
bridges between
metals. Reference is made to the Jahn–
Teller effect, but the figure describing
this effect makes no sense whatsoever.
Given that the constitutive molecular
properties in many cases dictate the
properties of the materials discussed,
these numerous errors at some level

undermine the creditability of the
book.
In summary, a strength of this book
is its intuitive explanations of onedimensional materials, and I will
undoubtedly use some of these ideas in
my own lecturing and teaching. Students
seeking to develop a rigorous scientific
foundation for an in-depth understanding of one-dimensional metals will
need to read the supporting references.
Researchers seeking guidance to the
current literature and clarification of
concepts will find it adequate for some
topics, but lacking for others.

Introduction to Solid-State NMR
Spectroscopy
By Melinda J. Duer.
Blackwell, Oxford

At present, solid-state NMR spectroscopy is one of the fastest-growing
research areas of magnetic resonance
spectroscopy. In the last decade, methodological improvements, along with
progress in hardware instrumentation
and sample preparation, have created
new opportunities for studying molecular structure and dynamics, ranging
from applications in biochemistry and
polymer science to geology. For a long
time, researchers interested in using
solid-state NMR spectroscopy had to
rely on the standard works by M. Mehring, C. P. Slichter, or R. R. Ernst et al.
These monographs provide all the theoretical tools needed to understand
modern solid-state NMR experiments,
