Core binding energy data for CF/sub 3/NC, Cr(CO)/sub 5/CNCF/sub 3/, and W(CO)/sub 5/CNCF/sub 3/ indicate that CF/sub 3/NC is a very strong ..pi..-acceptor ligand, practically as strong as CO. The core and fluorine lone-pair valence ionization potentials of CF/sub 3/NC and CF/sub 3/CN show that the net interaction of the fluorine lone-pair orbitals with other orbitals in these molecules is zero. The core data for CF/sub 3/NC and CF/sub 3/CN, when interpreted with the equivalent cores approximation, lead to a CF/sub 3/NC ..-->.. CF/sub 3/CN isomerization energy of -23 kcal mol/sup -1/.
