PREFACE TO THE
NINTH EDITION
This Survival Manual again presents the basic techniques of the organic chemistry
laboratory, with the usual emphasis on doing the work correctly the fi rst time. And
once again, I have relied on the comments of users and reviewers in guiding the
changes and additions that have been made.
Safety in the laboratory, always a primary concern, now has to consider the
addition of such technology as the iPad, the Nook, the Kindle, and even text mes-
saging, where applicable. Microscale, also where applicable, has been reviewed and
u pdated as well. And while currently resisting the deletion of double-beam spectro-
photometers altogether, a discussion of the technique of Attenuated Total Refl ectance
and associated practices has been added to the section on Infrared Spectroscopy
(Chapter 32).
The discussion and presentation of the section on Nuclear Magnetic Reso-
nance (Chapter 33) has been re-worked such that the different methods of sample
preparation, and instrument operation for continuous-wave and FT-NMR have been
made to contrast more sharply. A number of NMR spectra, with suggestions on pre-
sentation of the data, and basic interpretation have also been added.
Presentation of a more modern outline of the instrumentation of HPLC
( Chapter 31) includes discussion of automatic injectors, yet there is a bit of a loss
as this instrument, now highly computer-controlled, no longer has visible pumps,
valves, and miles of tubing and fi ttings, just a series of fairly quiet, putty-colored
boxes that produce excellent data with ease and a bit of boredom.
This kind of transition has put this edition of the Survival Manual into a bit of
an “equilibrium mode,” as now, at the urging of reviewers, some older techniques
have been removed as newer information has been included. The actual making of
TLC plates on microscope slides, which apparently needs not be done anymore, has
been removed, and comments about handling and cutting pre-prepared plates have
been updated and expanded (Chapter 27).
I’d like to thank my reviewers, Sean O’Connor, Clemson University;
Lucy Moses, Virginia Commonwealth University; Christine Rich, University of
L ouisville; Sean O’Connor, University of New Orleans; Jeffrey Hugdahl, Mercer
University; Kathleen Peterson, University of Notre Dame; Chavonda Mills, Georgia
College & State University; Beatrix Aukszi, Nova Southeastern University; Robert
Stockland, Bucknell University; Jennifer Krumper, UNC-Chapel Hill; Rui Zhang,
Western Kentucky University; Holly Sebahar, University of Utah; Adam List,
Vanderbilt University for their comments and suggestions, most of which have been

Chemistry and Physics, for the chance to perform this update, and Joan Kalkut,
Sponsoring Editor, for her tremendous patience and support during a personally
diffi cult time.
