This lecture
note set deals with basic issues in theoretical chemistry, such as specific
gravity, chemical nomenclature, atomic structure, and chemical bonding. The set
focuses on fundamental concepts in molecular chemistry, such as chemical
equations, the periodic law, and behavior of gases. The purpose is to develop a
robust understanding of the core topics from which deeper study is pursued in
theoretical chemistry, serving as an introduction for students at all levels.
This
lecture note explains fundamental concepts in quantum mechanics and
theoretical chemistry, particularly focusing on the electronic structure of
atoms and molecules. The document explores main topics such as many-electron
systems, quantum mechanical models, and their implications in understanding
molecular behavior. It provides a theoretical framework essential for
computational chemistry, aiming to bridge the gap between theoretical and
experimental chemistry. Topics discussed include the nature of electronic
structure, atomic and molecular orbitals, and quantum mechanics' role in
chemical reactions, forming the foundation of computational chemistry
approaches.

It
describes in detail the role of theory in chemistry. Key concepts covered
include chemical kinetics, oxidation numbers, electronegativity, and application
of various theoretical methods like quantum dynamics and classical Newtonian
dynamics. This note also underlines the importance of an interface between the
laboratory and theory inasmuch as experimental measurements interact with the
theoretical models. It discusses advanced topics such as mixed classical and
quantum dynamics, the Car-Parrinello method, and their applications to large
biomolecules and polymers, giving insight into the scope and methods used in
modern theoretical chemistry.
