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 $\nabla^2\rho$ to characterize …
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 …
How may I calculate the bond length between two atoms?
Apr 26, 2021 · Bond formation could be something like 1-P $_ {break}$. You could also run quantum calculations for all possible pairs (or higher order clusters) of atoms or hit the literature to look up …
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 …
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 …
visualization software - How to add a bond between two atoms in …
Jan 14, 2022 · Thank you for your comment. This method is ok now, but why VMD didn't draw the bond in the visualization. I have the two atoms without a bond between.
proteins - From a PDB file, how may I know which atoms have bonds ...
Sep 29, 2023 · A bond is present when the distance between two atoms is lower than the sum of the Van der Waals radii of the two atoms. Van der Waals radii are typically looked up from a preexisting …
Is it possible to do a Gaussian redundant scan with some fixed bonds?
Jun 18, 2021 · The last line indicates that the bond (B) between atoms 5 and 6 are scanned (S) with 20 steps of size -0.1 Angstrom. In the image you posted in the question, the bond between 5 and 6 is …
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 …
Simulating breaking bonds in molecular dynamics
Very short answer: No, classical molecular dynamics cannot break bonds. The potential you showed is the most common form of bond, the harmonic potential a.k.a. Hookes law. If you have ever broken a …
