`BASIC_ATOMS`

openff.pablo.ccd.patches.BASIC_ATOMS: dict[str, list[tuple[str, str]]]

Protonation variants that add an atom to the CCD.

Each 3-tuple specifies an atom name to protonate and the name of the added proton. A variant residue definition is created with that atom and bond added, and the formal charge of the atom increased by one.
