Write down the atom IDs of the first and second atoms of triple bond type molecules.
first atom refers to atom_id; second atom refers to atom_id2; triple bond refers to bond_type = '#';
SELECT T2.atom_id, T2.atom_id2 FROM bond AS T1 INNER JOIN connected AS T2 ON T1.bond_id = T2.bond_id WHERE T1.bond_type = '#'
