Ease of Use: 5 stars
Reviewed: Jul 22, 2001 by Chemistry Editorial Board
Overview: The site is well-organized and designed to provide a variety of spectra, such as IR,(1) H-NMR, (13)C-NMR, for a wide range of organic compounds. They are to be used by organic chemistry students to practice determining the structure of the compounds.
Type of Material: Drill and Practice

Evaluation and Observation

Content Quality

Rating: 5 stars
Strengths: Given the excellent IR section it is surprising that very few of the compounds have IR spectra information included.

This is an effective, well-organized tool for learning/teaching which can be used first as an introductory tool and then later as practice/drill tool. The narrative is clear and extensive and the graphics while not fancy are effective in presenting the spectra. The zoom feature works well and allows a good visul separation of close peaks. The search tool for specific compounds having specific functional groups is a good tool for a followup practice session
Concerns:

Potential Effectiveness as a Teaching Tool

Rating: 5 stars
Strengths: Large set of problems in increasing order of difficulty presented. Clear and extensive introductory text and explanations
Concerns: This is an excellent learning/practice tool and tutorial. The description of the layout, organization, and resources available is well documented. The IR spectra section includes a table of characterisitc frequencies for specific bonds which is very helpful in identifying unkowns. There is a feature giving the opportunity to compare IR spectra of two compounds. All the compounds contain (1)H and (13)C NMR spectra information and some have additional information in the form of IR, DEPT and COSY spectra.

Ease of Use for Both Students and Faculty

Rating: 5 stars
Strengths: Well planned and presented

Ability to zoom by clicking on specific peaks or by narrowing the range of frequency
Concerns: The user interface is excellent and therefore effective. The zoom feature is useful and works well. The IR table included is convenient and simliar tables for NMR spectra would have been useful
