On the whole covalently bound atoms have force constants at least an order magnitude greater than the intermolecular forces, and though many of the effects of condensation into a crystal or upon a surface can be observed by optical and other spectroscopic met

Writing and Reading in Henry JamesSec.5.2 with rotational motions of hydrogeneous molecules in crystals, and Sec.5.3 with rotation and diffusion in liquids and in liquid crystals. A common aspect in these problems is that such motions are responsible for energy transfers which are small compared to k.T, or to the Debye energy k.θ, a

Products of observation and imaginationwn in Chap.1, the coherent scattering of neutrons by a liquid is a measure of the correlated motion of the atoms in the liquid. Thus, the formalism developed in Chap.1 provides a convenient starting point for the discussion of collective effects in liquids. There it was shown for a classical liquid

Phonons,uctivity, for example, are related directly to the phonon density of states. Other properties such as the dielectric function, ultrasonics, the interatomic potentials (through the force constants) are more intimately related to the normal modes of vibration (phonons) of the crystal. These in turn ar
