The Structures of the Hydrogen Molecule and the Hydrogen Ion.
ON this mmorable and, beautiful occasion I bave the cherished honor of having been chosen to perform, as it were, the duties of chronicler, in order that we may all be led to review in our minds the successive steps by which our great leader and master rose to such high distinction and wrought the miracle of giving to medicine a new birth in this country; and in order, also, that our successors...
متن کاملThe Hubbard model for the hydrogen molecule
Using as an example the simplest case of a hydrogen molecule, the basis of the highly oversimplified Hubbard model is presented. This model attempts to understand the physics of both insulating and metallic systems in a unified picture, especially those metallic systems which include transition metals. The results of the analysis are compared with those obtained from independent electrons (delo...
متن کاملMagnetic dipole transitions in the hydrogen molecule
In homonuclear molecules, such as H2, the electric dipole transitions are strongly forbidden, and the transitions between rovibrational states are of the electric quadrupole type. We show however, that magnetic dipole transitions also take place, although are significantly weaker. We evaluate the probabilities of such transitions between several lowest rotational states and compare them with th...
متن کاملGerade-ungerade mixing in the hydrogen molecule
In homonuclear molecules, such as H2, the rovibrational levels close to the dissociation threshold do not have definite symmetry with respect to the inversion of electronic variables. This effect—the gerade–ungerade mixing—results from interactions between magnetic moments of electrons and protons. We calculate this mixing on the level of adiabatic approximation and numerically solve the system...
متن کاملAccurate adiabatic correction in the hydrogen molecule.
A new formalism for the accurate treatment of adiabatic effects in the hydrogen molecule is presented, in which the electronic wave function is expanded in the James-Coolidge basis functions. Systematic increase in the size of the basis set permits estimation of the accuracy. Numerical results for the adiabatic correction to the Born-Oppenheimer interaction energy reveal a relative precision of...
