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 …
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 …
