Fundamentals of NMR
This e-text presents an introduction to the fundamentals of NMR covering magnetic resonance, pulsed NMR, relaxation, chemical shift, spin-spin coupling, the nuclear Overhauser effect and chemical exchange.
NMR of Paramagnetic Proteins
This site presents an overview of techniques used for structural elucidation of paramagnetic metalloproteins. The content is directed to the more advanced NMR user and would be suitable for an upper division or graduate level NMR class.
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
This environmental PBL unit can be downloaded as a set of pdf\'s that include materials for students and an instructor\'s guide. These materials present a compelling environmental problem and analytical data that allow students to be educated as they work through the various tasks associated with identifying potential pollutants responsible for the reduction in fish within the Coley River. In addition, to providing the data necessary to solve the problem, the authors provide simple analytical sk
Amplified DNA Product Separaration for Forensic Analysts
This website is part of the President\'s DNA Initiative and is devoted to past and current methods of macromolecules such as DNA. This site reviews the analytical technologies of electrophoresis. Discussed are the differences between agarose and polyacrylamide electrophoresis. The basic principles of capillary electrophoresis and its advantages for conducting forensic DNA analysis are detailed. The site is designed as an on-line short course with excellent graphic support. The user must register
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
