- 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 bonding Standard QTAIM just uses the value of $\nabla^2\rho$ at bond critical points (minimum electron density along the bond, max along orthogonal directions), but these values are unintuitive and often don
- reference request - Bond Order: When and how is it used today? - Matter . . .
12 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 experimentalists
- visualization software - How to add a bond between two atoms in VMD . . .
I want to add a bond between specific atoms I found on VMD page that one can use topotools (e g topo addbond 1 2 ), but I have a lot of residues so this method didn't work with me I need to sele
- 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
- 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
- How may I calculate the bond length between two atoms?
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 experimental bond strengths for greater accuracy
- Scanning two bond lengths G-16 - Matter Modeling Stack Exchange
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 where you are scanning the bond lengths of C-Cl and C-H in chloromethane
- density functional theory - How to calculate homolytic bond . . .
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 compounds include
