- 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 Standard QTAIM just uses the value of ∇2ρ ∇ 2 ρ at bond critical points (minimum electron density along the bond, max along orthogonal directions), but these values are unintuitive and often
- Bond length from infrared spectra? - Matter Modeling Stack Exchange
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 bond lengths from IR alone, you can likely develop a correlation between a particular IR frequency and bond length for a series of related compounds
- Lost atoms in LAMMPS - Matter Modeling Stack Exchange
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 atom is lost But I know having a fixed z boundary is possible to run because that's what I found from several lammps papers
- 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 bond in QM (calculated a dissociation curve), you know it is a bit tricky, you need to use "unrestricted" settings, meaning, that a given pair of electrons does not need share the same orbital As
- Maximum bond length in Vesta - Matter Modeling Stack Exchange
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 atomic speci
- Is it possible to do a Gaussian redundant scan with some fixed bonds?
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 long, so during the scan, the bond length would have to decrease which is why the step size is negative
- How may I estimate the bond energy of a molecule?
Can I estimate the bond energy by running a single Gaussian calculation of the fragments at very long separation (say, 40 angstroms)? Or do I have to calculate each fragment without the other?
