Calculated Electron Affininty for BH (Boron monohydride)

Experimental Electron Affinity is 0.3 ± 0.25 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.
