vibration—vibration energy transfer in hydrogen molecules: H2(1) + H2(1) → H2(2) + H2(0)
Chemical Physics Letters, 1979Abstract The effect of molecular rotation and temperature dependence of energy transfer probabilities of the vibration—vibration process H2(1) + H2(1) → H2(2) + H2 (0) have been investigated using a semi-empirical potential in the probability expression obtained from an approximate solution of the time dependent wave equation.

Symmetric electron transfer reactions of state-selected ions: H2+ + H2 → H2 + H2+(ν= 0–10)
Chemical Physics Letters, 1984Abstract Total symmetric electron transfer cross sections for state-selected H 2 + ions were measured for vibrational levels of the ion from ν = 0 to 10 at a relative translational energy of 16 eV. The internal energy of the H 2 + ions was selected by threshold photoelectron—photoion coincidence using pulsed synchrotron radiation from the ACO ...

Electric dipole moment and energy in H2–H2 and H2–H collisions
The Journal of Chemical Physics, 1973The dipole moment and its derivative with respect to H2 internuclear distance were calculated for H2–H2 and H2–H collisions in the adiabatic approximation. A full configuration-interaction model with a minimum basis set of Slater orbitals was assumed in each case.

A surface hopping quasiclassical trajectory study of the H2+ + H2 and (H2 + D2)+ systems
Chemical Physics Letters, 1986Abstract In this work we use a complete surface hopping quasiclassical trajectory method to determine cross sections for the reactions H2+ + H2 → H3+ + H and the isotopic variants (H2+ + D2 and D2+ + H2). Initial translational energies ranged between 0.5 and 6 eV. The vibrational quantum number (v+) of the charged diatom is either 0 or 3.

Collision-induced absorption for H2-H2 and H2-He interactions at 5 μm
Journal of Quantitative Spectroscopy and Radiative Transfer, 1989Abstract Absorption coefficients for collision-induced spectra of H 2 have been measured at 299 K between 1830 and 2260 cm -1 . The weak absorption of H 2 in this spectral range has been detected by using a 3-m long cell with pressures ranging from 80 to 215 bar.

Calculation of the hyperfine spectrum for H2Ne, H2Ar, H2Kr dimers.
Chemical Physics, 1981Abstract The weakly bound dimers H 2 Ne, Ar, Kr are treated such that the H 2 , rotation (quantum number j ) remains unperturbed except for orientational effects. The orientation of the ortho H 2 ( j = 1) is mainly influenced by the anisotropic forces between the dimer constituents.

The effect of D2/H2 substitution on the Nb n + + H2 reaction
The European Physical Journal D, 1999The effect of D2/H2 substitution on the reactions of niobium cluster cations Nb n + (n = 5 − 9) with hydrogen was studied using a Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer combined with a laser-ablation/supersonic-jet external ion source. For most cluster sizes, it has been found that the reactions of the Nb n + clusters with

Rovibrational energy transfer in ortho-H2+para-H2 collisions
The Journal of Chemical Physics, 2007We present the results of a full-dimensional quantum mechanical study of the rovibrational energy transfer in the collision between ortho-H2 and para-H2 in the energy range of 0.1–1.0eV. The multiconfiguration time-dependent Hartree algorithm has been used to propagate the wave packets on the global potential energy surface by Boothroyd et al. [J. Chem.

Vibrational dependence of the H2–H2 C6 dispersion coefficients
The Journal of Chemical Physics, 2005We use the sum-over-states formalism to compute the imaginary-frequency dipole polarizabilities for H2, as a function of the H–H bond length, at the full configuration interaction level of theory using atom-centered d-aug-cc-pVQZ basis sets. From these polarizabilities, we obtain isotropic and anisotropic C6 dispersion coefficients for a pair of H2 ...
