Atomic Spectroscopy in a Project-Based Lab
An article published in the \"ABCs of Teaching Analytical Science\" series of the journal Analytical and Bioanalytical Chemistry describes a project-based lab in which students investigate the distribution of Pb and As (from pesticides) in a contaminated apple orchard. Students have complete control of the lab, from designing a sampling strategy to using the primary literature to develop procedures for extracting the analytes and for their subsequent analysis by ICP-AES or ICP-MS.

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

Multiple Regression
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
