Symmetry, fact that there are a number of different positions in which the molecule can be placed, which look the same or are physically equivalent. For example, if we twirl the methane molecule by 120° about a C-H bond, it looks the same. It is often possible to derive, from the symmetry of the molecule, in

Time Dependence,d other properties of the time-independent states of atoms and molecules may be calculated. Now, we discuss change or time dependence. This means that we return to a topic mentioned at the very beginning of the book, when we discussed how spectroscopy, through Bohr’s postulates, led to recognition t

Variation et optimisation de formes of electron density and other properties of electrons in and out of molecules were determined from solutions to an equation similar to the wave equation. The consequences of this postulate have been verified in many applications, so we shall simply accept the elements of Schrodinger’s theory as cor

,Dérivation par rapport au domaine,rse have to confront several particles in three dimensions. In this chapter, we remove one restriction by considering three-dimensional one-particle problems. This will enable us to treat one-electron atomic systems in Chapter 6. Then in Chapter 7, we will turn to the quantum-mechanical treatment of

Variation et optimisation de formest for hydrogen, and all molecules, have more than one electron— although there are a number of one-electron ions. However, the results we obtain for the one-electron atoms will play an important role in our treatment of atoms, and eventually molecules, with several electrons. Problems related to the
