Above threshold photodissociation in H2 and H2+
A coupled equations approach is used to calculate the probabilities of photophysical processes in the ten photon absorption spectrum of H2 at wavelength A = 532nm At high intensities, ie, I~10~°W/cm~, it is shown that above threshold photodissocianon (ATPD) occurs readily m the B ~3]
متن کاملVelocity-changing collisions in pure H2 and H2-Ar mixture.
We show how to effectively introduce a proper description of the velocity-changing collisions into the model of isolated molecular transition for the case of self- and Ar-perturbed H2. We demonstrate that the billiard-ball (BB) approximation of the H2-H2 and H2-Ar potentials gives an accurate description of the velocity-changing collisions. The BB model results are compared with ab initio class...
متن کاملNuclear relaxation of H2 and H2@C60 in organic solvents.
The 1H nuclear spin-lattice relaxation time (T1) of H2 and H2@C60 in organic solvents varies with solvent, and it varies proportionally for H2 and for H2@C60. Since intermolecular magnetic interactions are ruled out, the solvent must influence the modulating processes of the relaxation mechanisms of H2 both in the solvent cage and inside C60. The temperature dependence of T1 also is very simila...
متن کاملPressure-induced superconductivity in H2-containing hydride PbH4(H2)2
High pressure structure, stability, metallization, and superconductivity of PbH4(H2)2, a H2-containing compound combining one of the heaviest elements with the lightest element, are investigated by the first-principles calculations. The metallic character is found over the whole studied pressure range, although PbH4(H2)2 is metastable and easily decompose at low pressure. The decomposition pres...
