15.6. Bond valence sums — Artemis 0.9.26 documentation …

The bond valence is a vector directed along the bond since it represents the electrostatic field linking the ions. If the atom is unconstrained, the sum of the bond valence vectors around an atom is expected to be zero, a condition that limits the range of possible bond angles. Strengths and limitations of … See more The bond valence method or mean method (or bond valence sum) (not to be mistaken for the valence bond theory in quantum chemistry) is a popular method in coordination chemistry to estimate the oxidation states of … See more The bond valence method is a development of Pauling's rules. In 1930, Lawrence Bragg showed that Pauling's electrostatic valence rule could be represented by electrostatic lines of force emanating from cations in proportion to the cation charge … See more It is possible to do these simple calculations on paper or to use software. A program which does it can be obtained free of charge. In … See more The basic method is that the valence V of an atom is the sum of the individual bond valences vi surrounding the atom: See more Introduction Although the bond valence model is mostly used for validating newly determined … See more It is possible by bond valence calculations to estimate how great a contribution a given oxygen atom is making to the assumed valence of uranium. Zachariasen lists the parameters … See more WebThe bond valence sum dialog. ARTEMIS provides a tool for computing a bond valence sum from a list of paths included in a fit. A set of paths to be included in the sum can be marked in a path list. From the Actions menu, selecting “Compute bond valence sum” will display the dialog on the right.
