Introduction to Molecular Mechanics by C. David Sherrill
This lecture note highlights molecular mechanics as a computational chemistry approach to the modeling of molecular systems. The fundamental concepts included are: force fields, stretching, bending, and torsional energies. It explains the different components of energy, including van der Waals interactions and electrostatic forces, and goes further to describe factors through which they were used in predicting molecular behavior. Sherrill has also covered challenges in fitting atomic charges and how to parameterize force fields. Consequently, there is an in-depth overview of the computational methods used for simulating molecular structures and reactions.
