Bond generates a bond between two specified atoms. The atom-spec must contain exactly two atoms, and the atoms must belong to the same model. (Connections between atoms in different models can be drawn with PseudoBond Reader.)
~Bond deletes all bonds among atoms in atom-spec (which may contain any number of atoms). Only bonds with both flanking atoms in atom-spec are deleted.
