III.D.6.a. (XVII.D.)

Calculated Electron Affininty for NO (Nitric oxide)

Experimental Electron Affinity is 0.026 ± 0.005 eV
Please note! These calculated electron affinity energies have the vibrational zero-point energy (zpe) included, but the zpe has NOT been scaled. Click on an entry for more details, including the ionization energy with a scaled zpe.
