  1. What are the types of bond orders? - Matter Modeling Stack Exchange

    Laplacian Bond Order This method is an extension of the QTAIM (Quantum Theory of Atoms In Molecules) concept of using the Laplacian of the electron density ∇2ρ ∇ 2 ρ to characterize bonding. …

  2. Interpreting electron localization function (ELF) results

    From the QTAIM analysis we got the the lead make a bond with one nitrogen atom at the nanostructure surface. This is due to the interbasin path together with the bond critical point between both atoms. …

  3. reference request - Bond Order: When and how is it used today?

    Why Bond Order? Bond order isn't terribly useful to a computationalist directly; however, it can be invaluable for translating Quantum Mechanical results into a framework thats readily understood by …

  4. How may I calculate the bond length between two atoms?

    Apr 26, 2021 · Bond formation could be something like 1-P break b r e a k. You could also run quantum calculations for all possible pairs (or higher order clusters) of atoms or hit the literature to look up …

  5. Scanning two bond lengths G-16 - Matter Modeling Stack Exchange

    May 9, 2023 · When you are scanning two bond lengths in Gaussian, you step once through the first bond scan, and complete stepping through the second bond scan. For example, consider the case …

  6. Bond length from infrared spectra? - Matter Modeling Stack Exchange

    Jul 26, 2020 · If you know the bond lengths of few such compounds, you can derive a very accurate linear correlation between the bond length and the frequency. So while you can't directly predict …

  7. Lost atoms in LAMMPS - Matter Modeling Stack Exchange

    Nov 1, 2022 · HI @Magic_Number, after running with more recorded timestep, I think the main reason is because the molecule pass through zlo and have atom deleted, as result, the bond connecting that …

  8. What is the bond length of O2--? - Matter Modeling Stack Exchange

    Jan 28, 2023 · The real bond length could be obtained by doing a CBS extrapolation using FCI-level calculations with aug-cc-pCV8Z and aug-cc-pCV9Z, then adding corrections for relativity, QED, Born …

  9. density functional theory - How to calculate homolytic bond ...

    May 25, 2020 · An experimental colleague asked me how hard it would be to calculate homolytic bond-dissociation energies for different phosphonates which are involved in a Hydrophosphination. The …

  10. Maximum bond length in Vesta - Matter Modeling Stack Exchange

    Dec 30, 2022 · I need some cutoff radii to count bonds between different atoms in my system. When a .cif file is opened in Vesta, there are some default values of min and max bond lengths between two …
