Phonon Calculations in Metals and Insulatorsle field of inorganic, and organic crystals. In practice the situation is exactly the reverse because calculations have, in fact, been restricted only to simple metals, i.e. metals without partly filled . shells, except for few cases which shall be discussed either briefly here or in L.J. Sham’s lectures.

Optical Absorption and Photoemission Experiments on Metals and Alloysmen surface. The amount of reflected, transmitted or absorbed intensity as a function of frequency can be detected as well as the change of polarization state. From this kind of information the absorbed energy at frequency ω per volume and time, .(ω), can be deduced. Classical electrodynamics gives for this quantity:

The electronic contribution in simple metals has been fairly satisfactorily treated by the method of pseudopotentials, essentially treating the electrons as n
