Patrick Fleming

An open quantum chemistry text linking models of atoms and molecules with vibrational and rotational spectra.

Prerequisites

General chemistry, introductory mechanics and waves, and calculus including derivatives and integrals. Basic differential equations and vectors are helpful; the opening review uses mathematical physics immediately.

Reading Guide

Who this book is for

Chemistry undergraduates studying the quantum-mechanical part of physical chemistry, especially readers who want to connect equations with observable spectra. It suits a first quantum chemistry course after the mathematical and physical foundations, with group theory developed alongside molecular applications.

Prerequisites

General chemistry, introductory mechanics and waves, and calculus including derivatives and integrals. Basic differential equations and vectors are helpful; the opening review uses mathematical physics immediately.

What it covers

The contents proceed from classical foundations and the particle in a box to symmetry, molecular vibrations and rotations, hydrogen, approximation methods and electronic structure. Spectroscopic applications accompany the models, helping readers connect idealised energy levels with molecular behaviour.

How to use it

Work through the foundations and particle-in-a-box chapters before moving to group theory and the vibrational and rotational models. Derive each energy expression, check its units, and identify the assumptions. Then sketch the transitions the model permits. Use the chapter problems to decide which mathematical foundations need revision.
