I like this book. I think it is an excellent text for a
beginning student or research person starting or thinking
about using NMR as a method to obtain structural
information about organic molecules. There are 15 chapters, which
include topics such as obtaining an NMR spectrum; symmetry;
1H and 13C spectra of toluene; correlating proton chemical
shifts with molecular structure; chemical shift correlations for
13C and other elements; first-order (weak) spin-spin
coupling; second-order (strong) coupling effects; dynamic
processes; double-resonance techniques; two-dimensional NMR;
NMR of biologically important molecules; solid-state NMR;
and NMR imaging.
The format is a two-column presentation that is
very easy on the eyes. I particularly like the presentation on
two-dimensional NMR. It flows smoothly and reveals the
usefulness of the technique without undue mathematics.
At first I questioned the appearance of 60 MHz
1H and 20 MHz 13C spectra taken from the Sadtler Research
Laboratory collection of spectra. However, they are well used
in demonstrating the need for higher-field spectrometers
and the shift to first-order spectra. The text also uses
questions (with answers!) and two self-tests to monitor one's progress.
I did detect a few items that need to be corrected.
(i) On page 113, "If the neighboring nucleus had
I = 0, it could adopt only one orientation in a magnetic field." I
understand I = 0 to mean the nucleus does not have a magnetic
moment and therefore does not have a preferred orientation in a
magnetic field. (ii) On page 201, "a component of M
precessing on the +y¢ axis is ultimately detected as a positive signal,
while a component precessing on the
+x'or {x' axis gives zero signal." My experience is that one detects an
out-of-phase signal. Furthermore, the reference to Figure 3.22 in this
regard is misleading. Figure 3.22 deals with spin inversion and
not phase detection. (iii) The periodic table in appendix 2 has
a wealth of information but is very difficult to read owing
to the small print. The text does not go beyond the vector
model description of NMR and there is no mention of the
product operator formalism. Furthermore, neither the Bloch
equations nor the names of Bloch, Purcell, or Ernst appear in the text.
In summary, the book is an excellent starting point for
a student with an interest in obtaining structural
information about organic molecules to obtain an understanding of
the wealth of information obtainable from NMR spectroscopy.
