Addresses quantum states of molecules in terms of rotation and vibration of diatomic molecules
Among the topics he discusses are why to record the spectra of astronomical objects, atomic hydrogen, helium spectra, alkali atoms, spectra in magnetic fields, molecular structure, rotational spectra, and the electronic spectra of diatomic molecules
Most of those collisions involve diatomic molecules
of nitrogen and oxygen, gases that make up about 99 percent of the atmosphere.
Discussion includes dynamic variables and operators, the eigenvalue problem, quantum systems, the wave function, tunneling, particle in a box, light emission and absorption, two-particle systems, angular momentum, diatomic molecules
, the hydrogen atom, the electron and spectroscopy, the electronic structure of molecules, and nuclear magnetic and electron spin resonance.
Instead, the mystery element exists mostly as a colorless, odorless gas made of diatomic molecules
(two identical atoms joined to form a chemical bond).
His book on atomic structure was known to many generations of chemistry students, while his book on diatomic molecules
and the later ones on polyatomic molecules became standard references for theoretical chemists worldwide.
Their topics include the method of least squares, determining the rotational constants by the spectroscopy of polyatomic molecules, determining equilibrium structures and potential energy functions for diatomic molecules
, and structures averages over nuclear motions.
Chapters cover theoretical concepts, instrumentation, measurements, individual elements, electron excitation spectra of diatomic molecules
, and applications.
In the course of lectures on vibrational spectroscopy, we present the fundamentals on diatomic molecules
and progress on to polyatomic species with higher symmetry.
Appendix D Information on Some Diatomic Molecules
for the Identification and Processing of Low-Temperature Plasma Spectra
It covers the basics of atoms, diatomic molecules
, atoms and molecules in static and electromagnetic fields and nonlinear optics.
