Lecture note on Physical Chemistry and Theoretical Chemistry
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.

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.
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.
