A great number of chemists are now using
spreadsheets for teaching and research. Numerous articles on the use
of spreadsheets in analytical, inorganic, organic, and
physical chemistry have appeared in this
Journal. For example, the graphing capabilities of spreadsheets have been used to
perform a second-order polynomial fit to the electronic
absorption spectrum of molecular iodine
(
Pursell, C. J.; Doezema, L. J. Chem. Educ.
1999, 76, 839). Virtually every
computer found in a faculty office, laboratory, or
student computer lab now comes equipped with spreadsheet
software. This effort by Billo, the second monograph to be published
recently on Microsoft Excel applications for chemists, is a useful
guide for those who know little or nothing about spreadsheets
and for those who have their own ideas for spreadsheet
applications but require technical training in
Excel.
The appendices contain an extensive collection of
macros and functions, and the book is accompanied by a
3.5-in. diskette containing worked examples. It is worth
mentioning, however, that the macros and functions are written using
the Excel 4.0 format. The latest version (Excel 97 for
Windows systems) uses the Visual Basic Editor, which replaces
macros. Lists of key words used in Visual Basic and new features
in Excel 97 are also provided in the appendices.
The book is thorough with respect to basic Excel
uses--the first 13 chapters are written in the same manner as
the user's guides that accompanied previous versions of
Excel. Excellent coverage is given to mathematical concepts
that form the basis of advanced Excel applications. Such
topics include calculus, differential equations, graphical analysis,
and regression. Chapters 14-17 cover chemical applications
(e.g., titration curves and kinetics) that rely on the
mathematical concepts previously mentioned.
Chapters 18-21 contain worked examples, mainly in
the area of analytical chemistry: titrations,
spectrophotometry, equilibrium constants, and kinetic data analysis. In
most cases, the reader is not led step by step through a
particular exercise. Rather, the input, output, and equations are
shown, along with the cell references used to obtain
the results. The author compares results with those obtained by
the use of canned analysis software, demonstrating
that Excel functions quite admirably for those who use analysis
software only occasionally. Spreadsheet software such as Excel is also
the tool of choice for the chemist who wants to truly
understand data analysis, thus avoiding the "black box syndrome" of
canned software. An added advantage of spreadsheets is the ability
they give one to customize these tasks for individual applications.
