Discusses in great detail aspects connected with the visual and mental processing of chemical images. Presents various types of conventions for translating three-dimensional objects into two-dimensional representations. (Author/CCM)

Describes an inexpensive molecular model which is small enough to manipulate and large enough to be seen by large audiences. Discusses models of atoms and double and triple bonds. (JM)

Treats the development of general stereochemical principles in historical fashion. Discusses work by Pasteur, van't Hoff, and Le Bel. Considers sugars by configuration, anomeric forms, ring forms, and conformational isomers. Presents numerous diagrams and thorough explanations. (MVL)

Presents an exercise to get students more intimately involved in the three dimensional nature of basic units by constructing models. Uses balsa wood, glue, sandpaper, and a square. Studies seven crystals: cubic, hexagonal, monoclinic, orthorhombic, rhombohedral, tetragonal, and triclinic. Plans are available for a Macintosh computer. (MVL)
