This advanced text introduces to the advanced undergraduate and graduate student
the mathematical foundations of the methods needed to carry out practical
applications in electronic molecular quantum mechanics, a necessary preliminary
step before using commercial programmes to carry out quantum chemistry
calculations. Major features of the book include: Consistent use of the system
of atomic units, essential for simplifying all mathematical formulaeIntroductory
use of density matrix techniques for interpreting properties of many-body
systemsAn introduction to valence bond methods with an explanation of the origin
of the chemical bondA unified presentation of basic elements of atomic and
molecular interactions
The book is intended for advanced undergraduate and first-year graduate
