Chemical Bonding in the C2 Molecule
Inorganics, 2023 Bonding in the C2 molecule is investigated with CAS(8,8) wave functions using canonical MOs. In a subsequent step, orthogonal atomic orbitals are constructed by localizing the CASSCF MOs on the two carbon atoms with an orthogonal transformation.

An Orbital Exchange Calculation of Chemical Bonding in Metals [PDF]
, 2021 This work calculates the chemical bonds in lithium metal and beryllium metal using the orbital exchange method, a method that recognizes that the two electrons of a bonding pair cannot be completely distinguished when their orbitals overlap to bond ...

Chemical Bonding Origin of Glass Formation in Metal-Organic Frameworks [PDF]
, 2022 Glass-forming metal organic frameworks (MOFs) have novel applications, but the origin of their peculiar melting behavior is unclear. Here, we report synchrotron X-ray diffraction electron densities of two zeolitic imidazolate frameworks (ZIFs), the glass-

Chemical bonding in representative astrophysically relevant neutral, cation, and anion HCnH chains [PDF]
, 2022 Most existing studies assign a polyynic and cumulenic character of chemical bonding in carbonbased chains relying on values of the bond lengths. Building on our recent work, in this paper we add further evidence on the limitations of such an analysis and

Effect of nanotopogranphy in direct wafer bonding: modeling and measurements [PDF]
, 2005 Nanotopography, which refers to surface height variations of tens to hundreds of nanometers that extend across millimeter-scale wavelengths, is a wafer geometry feature that may cause failure in direct wafer bonding processes.

Chemical bonding and Born charge in 1T-HfS2
npj 2D Materials and Applications, 2021 We combine infrared absorption and Raman scattering spectroscopies to explore the properties of the heavy transition metal dichalcogenide 1T-HfS2. We employ the LO–TO splitting of the E u vibrational mode along with a reevaluation of mode mass, unit cell

A note on Michael Weisberg’s: Challenges to the Structural Conception of Chemical Bonding [PDF]
, 2007 Weisberg’s (2007) recent paper on the chemical bond makes the claim that the chemical notion of the covalent bond is in trouble.
