Conclusions

  1. 1.

    The unrestricted Hartree-Fock method with corrected bond lengths was used to determine the equilibrium geometrical configurations of the radicals Z-HFC=NO. and E-HFC=NO..

  2. 2.

    The difference between the energies of the diasteromeric forms of the HFC=NO. radical is ∼1.6 kcal/mole; the Z form is the more stable.

  3. 3.

    When the Z-HFC=NO. and E-HFC=NO. radicals form from the diamagnetic molecules Z-HFC=NOH and E-HFC=NOH, the length of the =N-O bond decreases ∼0.15 Å, the C=N-O angle widens ∼10°, while the geometrical configuration of the HFC=N-group changes insignificantly.
