Functions
hypovalence | Returns the difference between the next-nearest target valence and the bond order sum. Returns None if valence targets are not defined. Includes hcount, but disregards aromatic flag. Returns error if target valences are available but none match. |
implicit_hydrogens | Returns the implicit hydrogen count for the atom, or None if the atom isn't a member of the valence model. |
targets | Returns valence target for Atom. Uses the valence model presented in Hydrogen Suppression in SMILES |
valence | Returns the sum of bond orders using this model: |
