extensive, and readable
account of empirically based computational approaches
to the structure and energetics of inorganic species although. by their own
definition. the title should have been
“Molecular Mechanics for Inorganic
Compounds”. since there is no coverage
ol‘ electronic structure methods whether
semi-empirical or ab-initio.
The text is essentially divided into three
sections. After a general introduction.
Part I (Chapters I - 5 ) deals with the theoreticaljmatheinatical basis of molecular
mechanics (MM). Part I1 (Chapters
6 - 14) with various applications, and
Part 111 (Chapters 15---17) with a series of
practical tips and guidelines for doing calculations and interpreting results. References are collated independently for each
part and are comprehensive, although the
layout leads to repetition and Refs. 288
and 289 from Part I1 are missing.
The material in Part I is reasonably
straightforward but is nicely presented.

for a text which assumes no prior knowledge of the subject. Probably the most
salient point which emerges in Part I (and
is consistently repeated throughout) is
that individual force field (FF) parameters need bear no relationship to their
spectroscopically determined counterparts. The FF parameters need to be taken as a whole and judged on their ability
to reproduce global quantities such as
molecular structure. The individual ‘ideal’
bond lengths. ‘ideal’ angles. force constants, etc. are not physically meaningful
in themselves.
The real meat of the text is contained in
Part I1 where an astonishing diversity of
applications is sampled, ranging from
computing structures for molecular visualization, through to estimating enantioselectivities; from racemate separations
and stereoselective synthesis to metal ion
selectivity; from combining M M calculations with spectroscopic measurements to
electron transfer reactions; from the
Jahn-Teller effect to bioinorganic chemistry. organometallics, and s-, p-. and fblock systems.
The applications naturally focus on the
authors’ own contributions, mainly in
transition metal chemistry. but this still
gives a remarkably wide and varied coverage--a testimony to their pioneering role
in this area. Together with selected examples from organometallic, main group
and f-block chemistry, the reader can certainly get a feel for the kinds of systems
and properties which can be modeled.
In many ways most of Part 111 becomes
almost self-evident from reading Parts I
and 11. but the authors take the time to
discuss some of the practical pitfalls encountered when attempting to apply M M
to inorganic molecules, especially transition metai systems, and while not being an
out-and-out plug for their program system MOMEC. one assumes it would be a
good vehicle for putting their philosophy
into practice.
The ultimate message is clear and definitely upbeat. M M can work even within
the richness and diversity of inorganic
chemistry provided you recognize its interpolative nature and work within this
constraint. This may be restrictive and
may also require the user to develop a
force field if none already exists for the
systems of interest. While this may not
always be for the faint-hearted, the authors make a compelling justification for
the success of M M and it is encouraging
to see just what can be achieved.
Overall, this book will appeal both to
the active research scientist and to the intellectually curious and is required reading for all those with an interest in theoretical approaches to inorganic systems.

According to Frank Press. past president of the U S. National Academy of Sciences: “Traditionally, young scientists
have learned about the methods and values of scientific research from personal
contact with more experienced scientists,
and such interactions remain the best way
for researchers to absorb what is still a
largely tacit code of professional conduct”. Recently. however. the increasing
size of research teams and the accelerating
pace of research have rendered such informal transmission of values insufficient.
Furthermore, the familiar “mad scientist” image is a false stereotype fostered
and encouraged by films, television, literature, and the sensation-seeking mass media. From the unrealistically optimistic
view of science and scientists as purveyors
of unlimited “better things for better living” (the motto of E. I. du Pont de
Nemours and Company), a backlash
against science has come to pass with a
