Determination of molecular structure in terms of potential energy functions from gas-phase electron diffraction supplemented by other experimental and computational data

Different approaches of equilibrium structure determinations by the gas-pha se electron diffraction (ED) method or by its combination with other releva nt techniques have been reviewed. Some problems and limitations of these ap proaches are discussed. Special attention is paid to various potential ener gy function models. Different types of equilibrium bond lengths obtained by the optimization of ED data or their combination with experimental and com putational spectroscopic data are compared in tables. Relations between dif ferent types of vibrational corrections are discussed. Structure data deter mined by other methods or approaches are given for comparison.
