This article describes the use of fluorine (19F) NMR for the analysis and structure determination of biomaterials. Using a traditional text-with-figures format, the article gives an overview of the synthesis of 19F spin-labeled materials and detailed descriptions of 19F chemical shifts and relaxation phenomena as applied to both primary and tertiary structure determinations of biochemical interest.
A Pictorial Representation of Product Operator Formalism: Non-Classical Vector Diagrams for Multidim
This site presents a pictorial description of the product operator formalism using a non-classical vector approach. This approach allows for the representation of any arbitrary multidimensional or heteronuclear NMR experiment. A description of a complete set of 16 vector representations for weakly-coupled two-spin (I=1/2) systems is given followed by an extension of this set to three-spin systems. Finally the concepts of coherence transfer, multiple quantum spectroscopy and phase cycling are ill
Tales of the Riverbank

Physical Chemistry Online
Physical Chemistry Online (PCOL) Is a collection of physical chemistry modules that address specific concepts in an open-ended, collaborative fashion. The PCOL collection contains fifteen guided inquiry modules covering five broad topics: thermodynamics, kinetics, polymers, computational chemistry, and spectroscopy. Many modules provide the students with an industrial context auch as the evaluation of raw materials or the development of new products. Students that participate in these modules ar
This site provides an introduction to the use of multiple regression, beginning with a glossary of important terms before taking the reader through a review of bivariate regression and the implementation and interpretation of multiple regression. One limitation to the site is its reliance on Minitab for calculations. Users, however, can reproduce the calculations using other software packages, such as SPSS or Excel. Prior knowledge of the basics of bivariate regression is assumed; thus, the site
primer on microscopes
This website is sponsored by Olympus company. It is similar to two other sites (one by Florida State University, the other by Nikon) already in asdlib whereby a common group of authors contributed to the development of all three sites. Thus, these sites are similar in content although differences exist. This Olympus site has a \"virtual microscopy\" that contains links to interacdtive tutorials that demonstrate the operation of different types of microscopes. Thus, one can compare how various
Concepts, Instrumentation and Techniques in Atomic Absorption Spectrophotometry
This pdf file contains a well written and thorough introduction to atomic absorption suitable for use by undergraduates and faculty teaching instrumental analysis courses. Topics covered in the document include theoretical concepts and definitions, flame atomic absorption, instrumentation, analytical interferences, sampling techniques, graphite furnace atomic absorption, and plasma techniques.
Virtual Crime Scene-Autopsy of a Murder
This site is designed to explore the interaction of crime scene investigation and forensic science Visitors are taken to a crime site where a murder took place. Relevant items of physical evidence are identified and the viewer is allowed to transport each item into a virtual crime. In the laboratory the viewer is allowed to select the appropriate technology to examine the selected item of evidence. Explanations are provided to educate the viewer on the theory and applications of a variety of for
Handbook of Basic Atomic Spectroscopic Data
This National Institute of Standards and Technology (NIST)) site containing atomic spectroscopic reference data. Information can be accessed through a variety of means, such as an interactive periodic table and dropdown lists of elements organized by name or atomic number. Data available include isotope abundance, electron configuration, nuclear spin, magnetic moment, ionization energies, spectral line wavelengths and intensities, and energy level information. References are also given.
NIST Engineering Statistics Handbook
This site provides a comprehensive electronic handbook on statistics for scientists and engineers. Topics include graphical approaches for exploratory data analysis, the characterization of measurement processes, the construction of statistical models for predicting and/or optimizing process, experimental design, process control monitoring, significance testing and the evaluation of product reliability. Although the site may be too detailed and complex for an undergraduate student to navigate wi
The Geometer's Sketchpad - Least Squares
This site provides a java-based demonstration of how a least-squares analysis works. The applet opens with a set of data points with a superimposed line. By clicking and dragging, the user can move the data points and change the slope and/or the y-intercept of the line. The residual error for each data point is shown as a square whose area increases the greater the vertical distance between the point and the line. A total sum-of-squares also is shown. By adjusting the slope and y-intercept, the
Cooperative Learning, Values, and Culturally Plural Classrooms
This webpage provides an introduction to cooperative learning by David and Roger Johnson who developed the technique. The article provides an overview of the cooperative learning method, discusses its educational benefits, and provides assessment data for its efficacy. The article also provides archival references to their work and others. As such the article is an invaluable resource for faculty interested in developing and implementing cooperative learning activities in their own classrooms
RCSB Protein Data Base
This website is an "Information Portal To Biological Macromolecular Structure". It is a protein data bank that contains a very large structural database in addition to providing a variety of tools and resources for studying the structure of biological macromolecules and their relationships to sequence, function and disease. A good starting point is to take the tutorial which explains how to use the site and its contents. This site contains meritorious information on biological macromolecules an
An overview of the Fourier theorem as applied to analytical measurements is given. The Discrete Fourier Transform and the Fast Fourier Transform algorithms are mentioned, and sampling requirements are discussed. Links are provided to descriptions of Fourier transform based mass spectrometry, infrared spectroscopy and NMR techniques.
Fundamental measurement PowerPoint
This site contains good images of basic general chemistry lab equipment and how to use them to make measurements (graduated cylinders, burets, thermometers, and balances). It could be useful for introducing students to laboratory work and measurements.
