Use your smartphone and a Google Cardboard viewer to visualize the 3D shapes of molecules as predicted by the Valence Shell Electron Pair Repulsion (VSEPR) model. Click on the models to explore the 3D shapes and their corresponding 2D representations. This app was created to help you understand and remember the predicted electronic geometries, molecular geometries, and bond angles for molecules with up to 6 electron regions around a central atom. Immerse yourself, explore, and learn. This app was created and developed at Tennessee Tech University by chemistry instructor Janet Coonce and computer science student Evgeny Vasilyev, in collaboration with TTU’s iCUBE, with significant contributions from chemical engineering student Savannah Hall and graphic art student Brandon
