3D Visualization for Teaching and Learning in Organic Chemistry: orbital hybridization and bonding

Abstract

This research focuses on developing techniques to create 3D visualizations for use in an electronic textbook. In this age of technology, traditional textbooks have become less appealing to the new generation compared to phones or tablets. Student learning can be enhanced by not only bringing the textbook online but also elevating the comprehensive experience for the students with 3D animations. We will show how animations of orbital hybridization and chemical bonding are made in Blender using Signed Distance Field (SDF) modeling. The orbitals’ models are mathematically combined allowing for smooth animation. We have used this technique to animate the transformation of atomic orbitals to hybrid orbitals and to show sigma and pi bond formation in Ethane, Propene, Acetylene, and Allene. This technique has the potential to illustrate other important bonding concepts such as resonance and aromaticity. We hope that this process helps guide those who would like to upgrade their teaching materials.
