Advanced text on Jack Simons' book deals with the concepts and applications
of theoretical chemistry. It deals with foundational quantum mechanics, model
problems, and characterization of energy surfaces. The book also discusses the
practical tools and methods used in theoretical chemistry, like quantum
dynamics, statistical mechanics, and chemical dynamics. It primarily focuses on
the computational techniques that support both theoretical research in chemistry
and discuss topics such as electronic structure, chemical kinetics, relationship
between the theory and experimental data.
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.
