This lab lets you explore the possible wave functions for particles in different potentials. Users can study a "particle in a box", vibrating molecules and more.

This applet simulates the operation of a cloud or bubble chamber. The user can select a number of decay modes, adjust the magnetic field to match the mode and measure radii or tracks in the chamber. A built in calculator assists the user in measuring particle energy.

The Stereo Molecule Viewer Project, Molecules are drawn in a 3d environment, can be projected in 3d using a geowall. The applet can also rotate, zoom, translate, and measure many parts of the molecule.

13C NMR spectroscopy is a powerful tool to help determine the structure of molecules in organic chemistry, by mapping the framework of C atoms in a molecule.

Many organic molecules exhibit characteristic vibrational modes that produce spectral features in the infrared region. These provide the experimental basis for identifying functional groups.

This lab presents the spectrum of eletormagnetic radiation in terms of wavelength and frequency.

This applet is used to explore the relationship between the isotopic ratios of an element and the element's atomic weight. Select any atomic element and manipulate its isotope ratios using the provided pie chart or table.

Mass spectrometers distinguish the chemical makeup of a sample by displaying the ratios of the different masses of particles within the sample. This applet is used to learn how mass spectrometry differentiates between different isotopes of an element. 

This applet simulates von Lenard's and Millikan's experiments which provided the experimental understanding of the photoelectric effect and eventual acceptance (albeit reluctant) of Einstein's quantum hypothesis.

Climate is regulated by the delicate balance of incoming and outgoing electromagnetic radiation. This applet first explores the climatic condition of various planets, focusing on Mars, Venus, and Earth.
