We have obtained improved values for the dissociation energies of molecular hydrogen and its ion by using a high-resolution pulse-amplified laser to probe the second dissociation limit. The onset of the
vibrational continuum is observed by state-selective detection of the atomic products of dissociation, and several auxiliary measurements link the results to the ground state. The dissociation energies are
accurate to 0:010–0:026 cm1, improving previous measurements by a factor of 3–7. Agreement with ab initio calculations is good for H2, D2, and their ions, but not for HD and HD. |
