Wintropy Logo Wintropy

This link downloads the Wintropy program used in the General Chemistry Sequence (Windows platform only). It models possible microstates in defined systems.

webtropy Logo Webtropy Online

This link points to an online version of Wintropy, which we call Webtropy. (It’s slower than the application version, but it runs on any platform).

Lesser Chemistry Programs–we don’t consider these as useful as the alternatives above, but they may be the off-campus only choice

Advanced Chemistry Development Labs
Makers of several chemistry-related drawing and visualization applications, including ChemSketch, a tool for drawing chemical structures which includes proton and C-13 NMR viewers. They also offer a 3D molecule viewer that aids in the visualization of chemical compounds.
