"Diffraction patterns, obtained by electron scattering of selected gaseous inorganic and organic compounds, with an emphasis on boron clusters, will be analyzed with the concerted use of ab initio calculations of various physical quantities, in order to obtain gas-phase molecular structures. A geometry in the gas phase has particular importance in that only intramolecular forces are responsible for it. This structural variations relative to a certain standard may be understood on the basis of well-defined intrinsic physical characteristics. The geometry and the intramolecular motion represent two parts of a three-concept phenomenon generally viewed as molecular structure. By studying dipole moments, conclusions about the electron-density distribution, the third aspect, can be drawn. Dipole moment studies have been applied successfully to derivatives of two-dimensional aromatic compounds."@en . " heteroboranes" . .
