Rigid Rotators: Molecular Rotational Spectraheir partial derivatives. Hence, this may be a good first example. Consider the simplest case: a diatomic molecule, e.g., the HCl molecule with one hydrogen and one Chlorine nucleus and 1 + 17 electrons. The full 20-body problem is extremely complicated, but at very low energies no excitations assoc

Another Example: Successive Polarization Filters for Beams of Spin ,= 1/2 Particlesore example of this type, an even simpler example involving spin . = 1/2 particles, hence, a 2 × 2-dimensional transformation. Suppose we have a beam of spin . = 1/2 particles. They can be prepared, so all are in a state of definite spin orientation, say, with .. = +1/2, or with .. =− 1/2, along som

Transformation Theory for Systems with Continuous Spectrarators whose spectra are discrete. Moreover, we have studied finite-dimensional subspaces of these vector spaces, so our unitary transformation matrices were finite-dimensional. Commuting operators, however, such as the operators ., ., . or the operators .., .., .. exist with continuous spectra. Sti

After an introduction of the basic postulates and techniques, the book discusses time-independent perturbation theory, angular momentum, identical particles, scattering theory, and time-dependent perturbation theory. It concludes

Schrödinger Theory: The Existence of Discrete Energy Levelsto a function of . only on the right-hand side. Because this must hold for all values of . and all ., the left-hand side and the right-hand side must be equal to a constant.We have separated the equation. The physical significance of the constant can be seen to be the energy, ..
