This purpose of this article is to explain, in simple terms, the difficulty students have in a British sixthform course in proceeding from X-ray photograph to molecular structure. (HM)

Describes the components and the molecular structures of soaps and detergents and the way they work. (GA)

Describes the static and dynamic structural features for metal derivatives of cyclopentadiene. (SL)

Reviews molecular properties of sweet and nonsweet compounds. (SL)

Reviews current applications of the Favorskii rearrangement in the synthesis and study of strained molecules. (SL)

Discusses the problem of complete reduction of representations of infinite point groups. (SL)

Provides an application of a direct group theory method to the determination of the number and symmetry of M-C-O groups. The method is explained and three illustrative examples are given. (MR)

Compares average displacements of charged particles under thermal motion alone with those obtained by the action of an external electric field to develop a concept of "apparent charge" to approximate actual structural charge in an electrolyte solution. (SL)

Reviews the subject of the electronic structures of metals which produce magnetism. (SL)

Emphasizes the role that crystallography plays and has played in building up the body of chemical fact. Shows how the teaching of much of this material is illuminated by reference to crystal structures and crystallochemical relationships in all areas of chemistry. Discusses close packing, silicate structures, and salt hydrates. (CW)

Provides general background on basic concepts of systems theory. Discusses applications of systems theory to computational and inferential chemistry in molecular and reaction systems, systems analysis, and synthesis. Describes methodology for studying chemical systems by computer and gives advantages of an integrated computational environment. (JM)

Provides background information about paper. Describes the manufacturing process, chemical composition and structure, associated environmental effects, uses of paper, and recycling. (JM)

Ribonucleic acid (RNA) converts genetic information into protein and usually must be processed to serve its function. RNA types, chemical structure, protein synthesis, translation, manufacture, and processing are discussed. Concludes that the first genes might have been spliced RNA and that humans might be closer than bacteria to primitive…

Discusses the role of semiclassical theory in chemical physics both as a computational method and conceptual framework for interpreting quantum mechanical experiments and calculations. Topics covered include energy wells and eigenvalues, scattering, statistical mechanics and electronically nonadiabiatic processes. (JM)

Describes current methods for the synthesis of DNA. Also describes the use of DNA as a highly specific molecular probe and as an agent for the mutation of genes. (DH)
