Book Description
The principal results of the work are as follows: 1. A simplified technique was devised for obtaining Raman spectra of powders. 2. The Raman and infrared absorption spectra of the following oxides were investigated: AsP3' SbP3' As 0 - SbP5. Te02. Ge02 (two forms) in the crystalline state, and ASP3' Ge02' Te0 in the glassy state. 2 5 2 3. The vibrational spectra of the crystalline and glassy forms of the oxides ASP3' Ge02' Te02 are simi lar in many main respects, indicating a similarity of their structural units which determine the vibrational spec tra of these substances. 4. By a study of the vibrational spectrum it was shown that arsenious anhydride has a molecular structure and consists of As0 molecules having symmetry of the point group Td' The force constants and vibration fre 4 6 quencies of the As 0 molecule were calculated. and the vibrational spectrum of arsenious anhydride was re 4 6 liably interpreted with the aid of these results. 5. A similar result was obtained for antimonous anhydride. consisting of Sb0 molecule.s with symmetry 4 6 ofthe point group Td. The force constants for this molecule were found and the vibrational spectrum was calculated.

Book Description
The General Assembly of the International Union of Theoreti cal and Applied Mechanics decided in Cambridge, United King dom, in 1982 to arrange the Symposium on Optical Methods in the Dynamics of Fluids and Solids. This decision was stimu lated by the fact that optical diagnostic methods are a more and more important tool in experimental mechanics. In contrast to the foregoing Symposium in Poitiers. 1976, which was devoted exclusively to optical methods in the me chanics of solids, it was a fruitful idea to bring together during the present Symposium scientists engaged in optical methods in the dynamics of all phases. It was proposed by the International Scientific Committee of the Symposium that contributions in experimental fluid dynamics should deal with transition from laminar to turbu lent flow, compressible fluid flow including high temperatu re flow, non-equilibrium phenomena in fluid dynamics and the interaction of fluid flow with solid boundaries and bodies. As regard. the mechanics of solids, the contributions should deal with the application of optical methods in the wave propagation in shock loaded bodies, in phenomena connected with the fracture mechanism, in nonstationary Vibrations of elements and parts of systems and in nonstationary strains in structures. The International Scientific Committee preferred to avoid invited lectures and in cooperation with the National Com mittees of IUTAM called for contribution from individual countries.

Book Description
The study of the vibrations of polyatomic molecules has recently turned into one of the most widespread and powerful methods of studying molecular structure. These vibrations ap pear directly in the infrared absorption spectra and Raman spectra of gases, liquids, and solids. A measurement of the number of bands in addition to their positions (frequencies or wavelengths) offers the possibility of obtaining a great deal of important information regarding the geometric and mechanical properties of the molecules, the types of chemical bonds, and so forth. It is now quite difficult to list the vast number of specific problems solved by measuring vibrational fre quencies. As a result of the successful development of research methods and the widespread applica tion of vibrational spectra in analyzing the structures of molecules and the constitution of ma terials, it now becomes necessary to develop the theory of molecular vibrations further. Existing theory, of course, is based on the assumption of the harmonicity of molecular vi brations, which, strictly speaking, is not justified experimentally. The anharmonicity of the molecular vibrations has therefore to be taken into account by introducing appropriate approxi mations. Thus, in carrying out calculations on the vibrations of polyatomic molecules, one uses the force constants calculated from the observed frequency values. However, as a result of the anharmonicity of the vibrations, the values of the observed frequencies differ from the harmonic values, and the force constants used therefore differ from the true ones, i. e.

Book Description
This collection of articles contains a systematic outline of original experimental and theoretical research on photoproduction of neutral pions at protons and at a strongly bound system of a few nucleons, i.e., the helium nucleus. Spark chambers and their use as spectrometers for photons and electrons are described in detail. The articles of the collection include information on a novel method of determining the efficiency of recording apparatus by generating monochromatic photons. The articles de scribe original theoretical research on the optical anisotropy of nuclei. Problems encountered in experimental studies of operating the synchrotron as a storage-type accelerator of electrons and positrons receive particular attention. The results of this research work are listed, and the problems of oppositely directed electron-positron beams in the 250-MeV synchrotron are considered. The articles should be of interest to physicists, including research workers, teachers, engineers, graduate students, and students in advanced undergraduate courses. v CONTENTS Photoproduction of Neutral Pions at Nucleons and Nuclei B.B.

Book Description
The first part of this collection sets out the results of some experimental and theoretical investigations into the optical properties of nontransition metals. The extensive future pros pects of metal optics are indicated; the use of metal optics enables a whole series of import ant electron properties of metals to be determined. Results obtained by studying intermolecular forces (the hydrogen bond and van der Waals forces) using spectroscopic methods (Raman effect and infrared absorption) are presented in the second part. A method of studying the true absorption of the drop phase of a water cloud is described. Methods of increasing the dispersion of manufactured spectral instruments and constructing various infrared spectrometers are indicated. The publication is intended for scientific workers, graduates, and students concerned with problems of metal optics, the electron properties of metals, and molecular spectroscopy. v CONTENTS OPTICAL PROPERTIES OF NONTRANSITION METALS G.
