Objectives
Following your study of this chapter, you should be able to:
 explain why transitions between quantum states must usually be described in probabilistic terms
 aproximate the force felt by one atom in the vicinity of another
 identify bound states, equilibrium separation and binding energy on a net potential energy curve
 define ionic and covalent bond and give examples of each
 calculate the allowed rotational and vibrational energy levels, Erot and Ervibr respectively
 estimate the effective force constant from a given spacing between vibrational energy levels
 calculate the total energy of a vibrationrotation system
 find the energy released by a photon during a vibrational transition
 discuss what causes band structure
 explain the what is meant by Raman scattering and why Raman spectroscopy is useful
 compare and contrast spontaneous and stimulated emission
 understand the basic mechanisms involved in the production of a laser, including the applications of three and fourlevel systems
 be familiar with some of the many scientific applications of lasers
 know qualitatively and quantitatively why atoms of a solid arrange themselves in a particular lattice structure
 write down the attractive and repulsive potential on each ion and know what causes each
 show that the mean separation between atoms in a solid is nearly proportional to temperatue in the classical limit
 compare thermal and electrical conductivities to obtain the WiedemannFranz law
 make corrections to find quantum mechanical result of the Lorenz number
 calculate magnetic susceptibility
 talk about the difference between ferromagnets, paramagnets and diamagnets and their relative values of magnetic susceptibility
 understand the relationship known as the Curie law, and at what range of B it applies
 state the two distinctive macroscopic features of a superconductor
 explain what is know as the "Meissner effect"
 talk about the similarities and differences between type I and type II superconductors
 site the important features of the BCS theory and some observed phenomena it successfully predicted
 know why if you have found one new superconductor, then you have probably found several
 have a basic understanding of Josephson junctions and other applications of superconductor
