Representing quantum mechanical states and observables allowing for the translational symmetries and the localizability of particle introducing the rotational symmetries key eigenfunctions and kets… Expand

In the approximation that every inertial observer experiences a homogeneous, uniform flow of time and sees a space that is Euclidean, the arena of physics is Minkowskian and one speed is the same in… Expand

IN CHAPTERS 15 AND 16, WE SAW THAT ELEMENTARY REACTIONS may be unimolecular, bimolecular, or termolecular. In a unimolecular step, a molecule with excess energy concentrates enough energy in the bond… Expand

IN CARRYING OUT CHEMICAL PROCESSES, one is concerned not only with whether a reaction can take place but also with the speed of the reaction. This must generally be neither too slow nor too fast. One… Expand

IN A HYDROGENLIKE ATOM, the electron is bound to the nucleus by a Coulomb potential. This has the form
$$V(r) = - \frac{{Z{e^2}}}{{4\pi \varepsilon r}},$$
(12.1)
where r is the interparticle… Expand

ACCORDING TO CLASSICAL MECHANICS, each infinitesimal part of a given system is localized at a point at any given time. As time progresses, this point travels along a definite curve at a determinable… Expand

A CHEMICAL REACTION GENERALLY INVOLVES rearrangement of the electron structures about atomic cores. Bonds between atoms may be broken and reformed. One or more elementary processes may be involved.
