The anharmonicity of the hydrogen-bonded (N … H) and proton-donor (C—H) stretching modes of the linear (HCN)3 species are calculated at the SCF level with the 4-31G and 6-31G** basis sets. Third and fourth energy derivatives and second and third dipole moment derivatives, which are needed to calculate the anharmonic terms, were evaluated by means of the one-dimensional Chebyshev polynomial fitting to the calculated ab initio points. Frequencies and intensities of overtone bands are reported and the effect of geometry relaxation on the polynomial fitted derivatives as well as mechanical anharmonicity on the vibrational intensities discussed. Key words: H-bonding, anharmonicity, vibrational frequencies, intensities.

Directivity Patterns

A rigorous theory of radiation from an elementary dipole located at the boundary or inside a plane-layered structure is considered. For a specific case of radiation from a dipole located at the free boundary of one film, a method of analytical simplification of the solution is demonstrated. This method made it possible to reduce the formulas for the emitted fields to one-dimensional integrals, which greatly simplified the analysis of the problem and accelerated the numerical calculations. As a specific technical application of the theory, the directivity patterns of point emitters (molecules, nanostructures) located on the free surface of a metal film in the Kretschman scheme and having an induced dipole moment along the film surface were obtained. The influence of the surface wave on the directional properties of the radiators is determined.

A Chain

By using Green's functional method, we investigated the influence of different strength constants at defected bonds and the junction's size on the transmission properties of the lattice wave in a one-dimensional chain. The heat currents of several defected chains are also calculated. The results show that correlation transmission between two defected bonds in a chain different from electron behaviors. Furthermore, for a large-size junction embedded in a chain, the transmission of high frequency phonons will disappear while having smaller strength constant in the junction than in two semi-infinity chains. On the other hand, for larger strength constant than in two semi-infinite chains, all phonons can transport through the junction with a certain transmission value, although the number of transmission peaks decreases. Finally, the lower frequency lattice waves have better transmission through a junction with a series of strength constants according to the Fibonacci sequence.

“Dynamical mixing”, i.e. relaxation of a stellar phase space distribution through interaction with the mean gravitational field, is numerically investigated for a one-dimensional self-gravitating stellar gas. Qualitative results are presented in the form of a motion picture of the flow of phase points (representing homogeneous slabs of stars) in two-dimensional phase space.

Ferroelectric Domains

Recent progress in the electron-mirror microscopy (EMM), e.g., an improvement of its resolving power together with an increase of the magnification makes it useful for investigating the ferroelectric domain physics. English has recently observed the domain texture in the surface layer of BaTiO3. The present authors ) have developed a theory by which one can evaluate small one-dimensional electric fields and/or topographic step heights in the crystal surfaces from their EMM pictures. This theory was applied to a quantitative study of the surface pattern of BaTiO3).
