Theoretical Determination of the Dissociation Energy of Molecular Hydrogen.
The dissociation energy of molecular hydrogen is determined theoretically with a careful estimation of error bars by including nonadiabatic, relativistic, and quantum electrodynamics (QED) corrections. The relativistic and QED corrections were obtained at the adiabatic level of theory by including all contributions of the order α(2) and α(3) as well as the major (one-loop) α(4) term, where α is...
متن کاملDissociation energies of molecular hydrogen and the hydrogen molecular ion.
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 e...

متن کاملNonequilibrium rovibrational energy distributions of hydrogen isotopologues in an expanding plasma jet.
State resolved densities of high rovibrationally excited hydrogen isotopologues H(2), HD, and D(2) in the electronic ground state have been measured in a supersonically expanding plasma jet. The obtained state distributions differ substantially from thermal equilibrium. Moreover, the distributions are not the same for H(2), HD, and D(2) indicating different formation and relaxation rates for ea...
متن کاملRaman Vibrational Shifts of Small Clusters of Hydrogen Isotopologues.
Raman vibrational shifts of small parahydrogen (pH2), orthodeuterium (oD2), and paratritium (pT2) clusters with respect to the free molecules are calculated by combining a first order perturbation theory approach with Langevin equation Path Integral Ground State (LePIGS) simulations [ J. Phys. Chem. A 2013 , 117 , 7461 ]. Our theoretical predictions are compared to existing cryogenic free jet e...
