Geometrical parameters for pyridine have been calculated using the 6-31G, 6-31G\*(5D), 6-31G\*\*(6D), and 6-31G(2 x 6D) basis sets. Comparisons are made with a microwave substitution structure and with results of other ab initio calculations reported in the literature. Particular attention is paid t

β¦ Synopsis
A comparison of the calculated semi-empirical (INlXQ potentials for torsiond rotation about carbon-carbon bonds in butadiene, g&ox& biphenyl, 2,2'-difluorobiphenyl and benzaldehyde with and without consideration of extensive geometrical optimization indicates the importance of this consideration especitiy for the larger systems.

The geometrical parameters for benzene, fluorobenzene, and cyanobenzene have been calculated using the 6-31G\*(5D) and 6-31G\*\* basis sets, and, in addition, the 6-31 + G\*(5D) basis set in the case of fluorobenzene. Compared to previous results obtained using the 6-31G basis set there are minor ch
A ray acoustics approach to flow effects on acoustics scattering is considered, based on a combination of geometrical acoustics and the paraxial ray approximation. The approach allows for scattering by objects of arbitrary shapes, inhomogeneous and moving media. Applications to flow effects on scatt
