The hydrogen atom in the hydrogen molecule

International Journal of Quantum Chemistry, 2009
Accurate two-electron wavefunctions which are localized in the sense that they are least distorted from a product of hydrogen atom wave functions, have been calculated for the X, 1∑+ and the b3∑+ states of H2 at nuclear separations of 1.0 to 4.0 bohrs. The calculations were done in the full configuration interaction approximation.

Reactions of Hydrogen Atom with Hydrogen Peroxide

The Journal of Physical Chemistry A, 2007
Rate coefficients are calculated using canonical variational transition state theory with multidimensional tunneling (CVT/SCT) for the reactions H + H2O2 --> H2O + OH (1a) and H + H2O2 --> HO2 + H2 (1b). Reaction barrier heights are determined using two theoretical approaches: (i) comparison of parametrized rate coefficient calculations employing CVT ...

Hydrogen-Like Atoms

2018
In a history of quantum mechanics, it was first successfully applied to the motion of an electron in a hydrogen atom along with a harmonic oscillator. Unlike the case of a one-dimensional harmonic oscillator we dealt with in Chap. 2 however, with a hydrogen atom we have to consider three-dimensional motion of an electron. Accordingly, it takes somewhat

Engineering the Coordination Environment of Single-Atom Platinum Anchored on Graphdiyne for Optimizing Electrocatalytic Hydrogen Evolution.

Angewandte Chemie, 2018
Two Pt single-atom catalysts (SACs) of Pt-GDY1 and Pt-GDY2 were prepared on graphdiyne (GDY)supports. The isolated Pt atoms are dispersed on GDY through the coordination interactions between Pt atoms and alkynyl C atoms in GDY, with the formation of five-

Radical Cyclization of Alkene-Tethered Ketones Initiated by Hydrogen-Atom Transfer.

Angewandte Chemie, 2018
An unprecedented C-C coupling reaction between alkenes and ketones by hydrogen-atom transfer, using Fe(acac)3 and PhSiH3 in EtOH, is described. This mild protocol features high site selectivity and allows the construction of sterically congested ...

Hyperpolarizability of the hydrogen atom

Physical Review A, 1987
The frequency dependence of the hyperpolarizability (\ensuremath{\gamma}) of the nonrelativistic hydrogen atom is calculated for a range of third-order nonlinear optical processes using an expansion in Sturmian functions. It is shown that the quantitative relations between the various nonlinear optical processes are made much clearer when \ensuremath ...

Visible-Light-Mediated Metal-Free Hydrosilylation of Alkenes through Selective Hydrogen Atom Transfer for Si-H Activation.

Angewandte Chemie, 2017
Although there has been significant progress in the development of transition-metal-catalyzed hydrosilylations of alkenes over the past several decades, metal-free hydrosilylation is still rare and highly desirable. Herein, we report a convenient visible-

The Hydrogen Atom

2012
Some of the problems that were the center of discussions during the long genesis of the quantum theory were the atomic structure and the radiated spectral lines, in particular the emission lines of Hydrogen. A convincing explanation of this problem had to wait to the advent of the quantum theory.
