Computational chemistry is a broad area of research that spans from quantum scattering to biomolecular modeling and nanotechnology. This tutorial will give a general overview of some of the methods and areas of research in computational chemistry. We will briefly explain the theory used as a basis for predictive modeling in each area discussed. We will also mention some real-life applications and the more popular programs used to carry out these calculations. Tutorials focusing on many of these programs will follow later in the semester.
