Review

"The Use of Chemical Abstracts" begins with an introduction and thorough detailed explanation of the use of the indexes. The sound on the cassette tapes is of high quality and rather pleasant in listening characteristics. The pace of the sound commentary is lively yet not too fast for comprehension and of remarkable clarity. The technique of color emphasis on the slides not only makes for drawing one's attention to the particular detail a t hand but pro- vides added emphasis for the aid of the learner.

The level of detail is more than adequate for the researcher of the chemical literature, yet not so involved that the unit can be utilized for undergraduate seminars or as an independent unit of an advanced eourse where the user needs only access to a set of chemical abstracts in order to work out the problems which appear inthe accompanying workbook.

These are of an excellent nature and get to the core of the usage of chemical abstracts. Given this instructional unit, a cassette tape recorder and a slide oroiector alone with a set of chemical ab- . , - ~tracts , the learner can pursue this material a t his own pace which makes for good self-paced instruction, yet the unit is also well suit- ed for group use in a classllibrary setting.

The cost of the unit, although high, is not excessively prohibitive making this a sound investment for any undergraduate chemistry department andlor science library. The unit could also serve as a useful inclusion in a graduate course on searching the chemical lit- erature which may be given by a university either through its chemistry department or through its library. Minimal pre-prepa-

ration is required of the student hut the workbook provides sub- stantive follow-up and reinforcement of the overall objectives.

001-Bssic Principles. Pa r t I "This first lesson introduces the basic principles of infrared spec- troscopy and examines the single beam spectrometer. Topics cov- ered in the first half include the electromagnetic spectrum, the in- frared spectrum, molecular absorption, detection and measure- ment, and the types of infrared spectra. The second half is devoted to the optical and electronic components of the single beam spec- trometer. These include the source of radiation, prism and grating dispersion elements, detectors, and a typical tuned amplification system."

system performance. After a brief introduction on the concepts and advantages of the double beam spectrometer; the first section examines the optical components, detector output, and amplifier waveforms and how they differ from those of the single beam in- strument. The second half introduces a set of accuracy criteria for spectra and what these dictate in terms of signal-to-noise ratio, and scan time. Finally, the relationships between these perfor- mance criteria and the physical variables of slif width and re^

sponse time are explained."

003-Quantitative Analysis, P a r t 1 "The purpose of this lesson is to develop the relationship known as the Beer-Lambert Law and indicate how to obtain accurate ab- sorbance measurements for use in Beer-Lambert Law calculations. The first half illustrates the relationships between transmittance and concentration, absorbance and concentration, and between absorbance and cell path length. With this background, the Beer- Lambert Law is developed and used in several sample calculations. In the second half, the absorbance scale is introduced, baseline and observed zero corrections are discussed, and methods are indicated for estimating the baseline in scanned spectra."

004-Quantitative Analysis, P a r t 2 "This three-part lesson describes the analysis of multicomponent systems, points out techniques for improving the accuracy of in- Rared quantitative analysis, and discusses the effects of deviations from Beer-Lambert Law linearity. In the first section, the additiv- ity property of absorbance is derived and employed to analyze sys- tems of two components and n-components. Improving accuracy is seen tn involve the handline of svstematic errors. an understandine

as well as the use of working curves to circumvent these problems."

Review

I t should be noted that this series is not concerned with the practical aspects of obtaining a spectrum. While the basic princi- ples of instrument design are covered, no attempt is made to dem- onstrate proper adjustment of controls to optimize instrument perfbrmance.

The visual component of this package is of very high quality. The speaker is easy to listen to and the pace of the presentation is also adeauate. It is too bad that all of the taDes I reviewed are marred by what sounds like someone talking quietly in the back- ground. This could be distracting to someone using the material for self-study, although in a classroom it might not even be no- ticed.

The material lends itself nicely to self-paced instruction. Since each part begins with a clear statement of objectives and concludes 'with a review of what has been covered, the amount of pre-prepa- ration would be minimal.

The cost of the series is $70 per unit or $210 for the four pro- gram set. Compared to other cassette-slide programs available in the sciences. this is rather hieh. I t would be difficult, however, if

Shown are familiar events-friction, heat flow, melting, and combustion-backwards. A bowling ball springs suddenly into the air spontaneously; a red-hot penny cools in a flame until i t can be safely hand-held; formation of ice cubes warms surround- ing water to its boiling point; soot, smoke and flame make a newspaper page. The viewer is led to an appreciation of energy transformations and to a feeling for the implications in our ecol- ogical crisis of the Second Law of Thermodynamics. An exten- sive set of such questions with answers is included."

Review

Most chemistry teachers do not make sufficient use of the unique capabilities of films, and are understandably skeptical of the claims made for them. They should however give this short film a try. It is entertaining and it makes clearly its point on the second law of thermodynamics. Best of all i t will make you and your students think, and it can be effectively used to initiate a dis- c " s s ~ " ~ .

It is clearly aimed at thermodynamics classes in the sense that scenes are selected upon which entropy calculations can be made. This reduces the human element to a minimum, but not so far as to eliminate the dramatic effect. I personally almost jumped the first time I saw fingers take hold of a penny just removed from the flame.

Nevertheless the distributors are correct that the film can be ef- fective for audiences from grade school students through thermo- dynamics professors. Pre-school children who can't read will miss the point, but second graders can explain it after viewing it once.

This is an effective film, well done. You will probably, like me, want some things done differently, and the questions with the film encourage thinking about what additional scenes would be useful. However we would not feel this way about i t if i t were not very ef- fective as it stands. If there were more short films of this quality our excuses for not using films in upper division classes would evaporate.

The film comes with a list of 51 questions. The distributors state, "The film is primarily to stir up interest and to amuse and is not meant to be completely independent of the questions." I would advise you to allow the film to stir up an interest, and then proceed in whatever way is appropriate to your particular class situation. Do not destroy that interest by spending any substantial time with the questions. They contain some interesting ideas that can be added to a discussion, but the question form is not necessarily the best way to do this. Computing approximate values of S t o u t for some of the scenes photographed could be a homework assign- ment, but not necessarily any better than problems from the text- book. Fortunately the film is not limited to use in a particular way or with a particular set of questions.
