Symmetrized G- matrix elements for the pyramidal XY 2 Z molecular model are given. Force constants have been calculated for eleven mixed halides of phosphorus and two mixed halides of arsenic. An empirical relationship has been established for the. f

This is the first part of a work of systematic studies of molecular vibrations of various models. Some conventions are proposed as to the orientations of cartesian axes and degenerate symmetry coordinates, in addition to already existing (but not uni

A theoretic treatment is given for the planar ethylene-like (D2h) model, the corresponding twisted (right-angled) model (D2d), and the general case of D2 symmetry. The correlations between the various symmetry species which pertain to the molecular v

A normal-coordinate analysis has been performed for the molecular vibrations of B2Cl4. The force constants were used to calculate the mean amplitudes of vibration. Also the framework mean amplitudes for the long Cl···Cl distance was studied as a f

A theoretical analysis is given for the molecular vibrations of the following trigonal bipyramidal models: (iti) X3Y2 of D3h symmetry, (itii) (XZ2)3(YW)2 with planar (XZ2)3 structure (itD3h symmetry), and (itiii) distorted (XZ2)3(YW)2 of D3 symmetry.

The T(i) α,β,S s elements in the theory of centrifugal distotrtion are given for the linear XYZ and a number of four-atomic molecule models. For some of the most important ones of these models (viz. linear XYZ and X2Y2, planar and pyramidal XY3) al
