Avogadro double bonds math

Hello!

Not so far ago I have started to work in avogadro for my university degree.

So for now I have a quesion about how avogadro works with bonds. More precisely, I need an understanding of Ghemical mathematics for different number of bonds(C-C/C=C).
I will be very grateful if you tell me where to read to me about this!

First off, I wouldn’t advocate the Ghemical force field. It’s available because it’s an open source method.

Among other places, you can find information on the Open Babel website:
