Some aspects of molecular orientation in covalently-bonded molecular solids are discussed by reviewing a simple model for the molecular ordering of frustrated lattices. The model describes a peculiar… Expand

A number of experimental studies of condensed matter assemblies with different types of chemical bonding will provide the focus of this work. Condensed compounds X(CH3)4, with X = C, Si or Ge, are… Expand

This model of two-dimensional 5p-electron delocalization for crystalline iodine is examined as a function of pressure, by generalizing Rosenberg's assumptions to afford a natural explanation for the formation of a quasi-two-dimensional system for pressures greater than 21 GPa, recently observed by Mossbauer spectroscopy.Expand

Abstract A review is given of metal-insulator transitions induced by pressure in chemically bonded solids. After an introduction to energy band overlap mechanisms, which appear very useful to… Expand

Elemental iodine has been studied by /sup 129/I Moessbauer effect at 4 K to pressures of 30 GPa in a diamond anvil cell. Its structural transformations leading to metallization have been determined… Expand
