XVII.C.1.

Calculated Ionization Energy for SiC (silicon monocarbide)

Experimental Ionization Energy is 9.2 ± 0.4 eV
Please note! These calculated ionizataion 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.
