Bond paths are not chemical bonds.
This account takes to task papers that criticize the definition of a bond path as a criterion for the bonding between the atoms it links by mistakenly identifying it with a chemical bond. It is argued that the notion of a chemical bond is too restrictive to account for the physics underlying the broad spectrum of interactions between atoms and molecules that determine the properties of matter. ...
متن کاملTaxable Bond Investing: Bond Funds or Individual Bonds?
Introduction This paper primarily examines the advantages of bond mutual funds over portfolios of directly held bonds for both institutional and individual investors. First, we review the structural advantages of bond mutual funds, which, compared with separately managed and laddered portfolios of individual bonds, generally provide greater diversification; more regular cash flows that promote ...
متن کاملElectronic stress tensor description of chemical bonds using nonclassical bond order concept.
The stress tensors are used widely for description of internal forces of matter. For some time it is also applied in quantum theory in studies of molecular properties in chemical systems. Electronic stress tensors measure effects caused by internal forces acting on electrons in molecules and particularly those between bonded atoms. Utilized here stress tensor originated bond orders express bond...
متن کاملWeaker Bonds with Shorter Bond Lengths
One of the paradigms of chemistry predicts that the shorter the bond of a given type is always the stronger bond. Although this qualitatively holds for many compounds, there exists no general proof that this is always correct. Here, we discuss molecules, for which longer bonds lead to stronger rather than weaker bonds. This is possible by introducing the local mode stretching force constants as...
متن کاملCorrelation Analysis of Chemical Bonds
We present the methodology for correlation analysis of chemical bond operators (CACB) on ab initio wave functions. In CACB the wave function is analyzed in a hierarchy of quantities (charge, bond order, bondbond correlation), where each quantity is the expectation value of an operator related to the statistical covariance of the previous quantity. CACB does not require any preconceived notion o...
