visualization software - How to add a bond between two atoms in …
Jan 14, 2022 · 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 …
Maximum bond length in Vesta - Matter Modeling Stack Exchange
Dec 30, 2022 · Bond length is calculated by using atomic positions and lattice parameters. Ionic or covalent size do not matter, the distance will be always the same because it is between the …
Simulating breaking bonds in molecular dynamics
The sigma, pi and double pi bonds contribute increasingly to the overall bond order (max individual bond order is 1) as the atoms get closer together. For simplicity I am leaving out the …
