Title: Ionization Energy of H2 Molecule
Post by: phantom113 on December 15, 2008, 10:22:51 PM

What is the ionization energy of the H2 molecule?

15.42593 eV (electron volts).  I got this value from the NIST webbook.  Hope this helps

Yes, that helps, although not in a good way.  If you are given the bond energy of H2 and H2+ and the ionization energy of H, how would you go about finding the ionization energy of H2 from that information?

Thanks.
