Rdkit formal charge
WebAug 10, 2024 · Re: [Rdkit-discuss] Assigning formal charges. Hi Juuso, A quick solution that seems like it would covert most cases would be to construct a molecule from you input without doing sanitization, calculate the atomic valences in non-strict mode, and then to identify all neutral N atoms with a valence of 4 and add a positive charge to them Here's … WebIf an atom has a negative NUE, it needs a positive formal charge (-NUE). If two neighbouring atoms have UEs, the bond between them most likely has to be increased by the value of …
