Our attempt to present NMR spectroscopy to the beginner in a somewhat
different way was well-received, so that we were invited by Springer to make
some additionsto the original for a second edition. Naturally we have modified
the text to take account of justified criticisms of the first edition. We decided
immediately to extend the number and scope of the problems section
comprising Part 2, as we know that this section has been very useful to our
readers. We felt that solid-state NMR is now so important and so relatively
easy to do that it would bewell worth giving the reader a brief account of its
advantages and disadvantages. And, having already dealt with four important
nuclei in some detail, we decided to add some basic information on a number
of other spin-½ nuclei which are now often studied.
We thank Prof. Janet Blümel, Texas A&M University, and the Gesellschaft
Deutscher Chemiker for allowing us to reproduce solid state NMRspectra.
In addition we thank Klaus Jurkschat and Bernhard Lippert and their groups
for making available samples of organometallic molecules. Thanks also go to
Andrea Bokelmann and Bernhard Griewel for their valuable technical help.
Preface to the Second Edition
Why write another NMR book? Most of the many already available involve
theoretical approaches of various kinds and levels ofcomplexity. Few books
deal with purely practical aspects and a handful are slanted towards problem-
solving. Collections of problems of different complexity are invaluable
for students, since theory of itself is not very useful in deducing the structure
from the spectra.
However, there is now a huge variety of NMR experiments available which
can be used in problem-solving, in addition to the standardexperiments
which are a “must”. We start by providing an overview of the most useful techniques
available, as far as possible using one single molecule to demonstrate
which information they bring. The problems follow in the second part of the
book.
We thank Annette Danzmann and Christa Nettelbeck for their invaluable
help in recording the spectra and our wives Karin and Monika for their...
