For completeness, some papers involving the observation of pure rotational spectra in the far-IR regions, are included. Other reports consider the vibrational spectra of small symmetric species and of single crystals; characteristic vibrational frequencies of compounds containing main-group elements; vibrational spectra of transition-element compounds; and vibrational spectra of some co-ordinated ligands. Finally, in Chapter 8, R. Greatrex reports on Mijssbauer spectroscopy. The opening section covers books and review articles. This is followed by brief surveys of general theoretical aspects and developments in instrumentation and methodology. The main body of results is contained in the final sections which deal with studies on iron-57, tin-119 and other elements. W. J. 0. T. and Bonding, Vol. 17, edited by J. D.

Structure
This volume comprises four articles which deal with metal bonding in proteins. The first article considers structural aspects and biochemical function of erythrocuprein, one of the most actively studied copper proteins. Its preparation and characterization are discussed in detail before its enzymic function and possible role in metabolism are considered. The importance of iron in mammalian organisms is such that it is unnecessary to make a case for the study of this mineral and its metabolism. There are a number of iron-containing proteins in mammals and the second article considers one of these, namely ferritin. Its physiological function, structure and formation are dealt with. The mobilization of iron from ferritin, iron exchange between ferritin and transferrin and biosynthesis are also discussed. The following article deals with metal-polypeptide interactions: the conformational state of iron proteins. The siderochromes, transferrins, hemerythrin, rubredoxins and iron--sulfur proteins are all considered. Finally, calcium-binding proteins are discussed. Calcium probably fulfils a greater variety of biological functions than any other cation. The topic is introduced with a survey of calcium functions in living organisms, indicating potential sources of binding proteins. The article describes the wide variety of physiological functions of calcium proteins and the correspondingly large differences in their chemical structures and binding affinities. W. J. 0. T.
