An Introduction to Molecular Modelling
|
FREE TRIAL
|
VSEPRplex™ (pronounced "ves-per-plex") is an interactive chemistry package that helps students visualize and understand molecular geometry. While building and exploring their own 3-D structures, students encounter the shapes and properties of small covalent molecules. VSEPRplex™ was designed for use in senior high school and college chemistry courses. [long description]
