And finally, Dr. Timofey Tyugashev, who was the first to post his response to my query, perhaps put in a comma between "Bond" and "Dissociation" in the subject head, "[PyMOL] Is it possible in Pymol to determine Individual Bond, Dissociation Energy for any Bond in organic

Dear Rajib, Pymol reads atom labels and positions from a coordinate file. It then determines which atoms are bonded based on distance criteria. That is used to draw the molecule. Pymol also has an internal library of molecules and fragments, with atoms and bonds, which can be used to build bigger

Hi Rajib, Probably part of the confusion is due to the meaning of "determine the structure". I understand "determine" can have different meaning in different contexts. In my area of research "determine" generally means to use experimental methods like X-ray crystallography or NMR to establish the

No, Dr. Wassenaar, Sir! People have confused me. After two years, I am told that: [Quote]PyMol does not use QM methods. It also does not "determine the structures of molecules" [/Quote] I need my illustrious peers to clarify me regarding all my queries in all my posts in the present thread.

Hello, Illustrious Members! I have a query: Let us assume one is in possession of a particular named organic reaction. In that reaction a set of reactants change into a set of products. It is very easy to observe in those named reactions as to which bonds have broken down to form other newer
