Structure and Bonding

  • ChemTube3D (U. Liverpool) :  JSmol-based presentation of topics in structure and bonding, including atomic and molecular orbitals, VSEPR structures, and symmetry.

Symmetry and Point Groups

  • Otterbein College :  Jmol-based symmetry tutorial.
  • ChemTube3D (U. Liverpool) :  Follow the Symmetry links in the sidebar on this page for symmetry tutorials and examples.
  • Jacobs University Bremen :  Character tables for all commonly encountered point groups, as well as online tools for symmetry analysis; note that example molecules (with manipulable visualizations) are available under each point group (where such examples exist).
  • Gernot Katzer :  An impressive compilation of character tables with extensive discussion of properties and features, online tools for symmetry analysis, and listings of molecular examples (but without molecular graphics). What's the relationship between symmetry and spices? I don't know, but if you enjoy cooking (or dining), check out the spice descriptions on this site!
  • WebQC :  Character tables for all commonly encountered point groups.
  • Wikipedia - "Molecular symmetry" :  Wikipedia has a listing of molecular examples by point group; see also the external links at the bottom of that webpage for other online resources, as well as separate Wiki entries for "Point group" and "Point groups in three dimensions". N.b., Wiki entries are, of course, publicly edited.

Matrix Multiplication :  Formal Definitions

Matrix Multiplication :  Tutorials

  • Khan Academy :  An extensive tutorial on basic matrix manipulations.
  • Purplemath :  Another approach, again emphasizing process rather than theory.
