The isotope effect on the photoassociation of X + F → XF (X = H, D)

Abstract

The photoassociation (PA) reactions of H + F → HF and D + F → DF are investigated by using the time-dependent quantum wave packet method. For each system, we consider four cases, where the target state is set to be |ν = 16, 17, 18, 19〉, respectively. The effects of the initial collision momentum and laser parameters, including intensity, pulse duration, and frequency, on the final association probability are calculated and discussed. It is found that the PA probability for H + F → HF (|ν = 16, 17, 18〉) is significantly greater than that for D + F → DF (|ν = 16, 17, 18〉), while the PA probability to |ν = 19〉 for the latter system is greater than the former one. This isotope effect has been connected with the Franck-Condon overlap integral between the target vibrational state and the collision continuum state.

Microstructure evolution of periodic layers formed during solid state reaction between Zn and Ni3Si

“…2c and d). This phase transformation phenomenon is similar to that of the periodiclayered structure in the Zn/CuTi system [13]. Furthermore, the layers of phase Ni 4 Si 3 Zn 12 will be "eaten" gradually by the neighboring layers of phase d-Ni 3 Zn 22 , and at last only the thicker layers of phase d-Ni 3 Zn 22 (Ni 12.4e12.5 Si 1.3e2.5 Zn 85.1e86.2 ) exist within the zone near to the Zn substrate ( Fig.…”

Catalytic Performance of Layered Double Hydroxides (LDHs) Derived Materials in Gas‐Solid and Liquid‐Solid Phase Reactions

“…Methanol is one of the topmost raw chemical used in industry attracting more and more attention as it can be easily obtained from natural resources. For its proper utilisation, methanol can be selectively transformed to valuable products such as olefins, dimethyl ether (DME), dimethoxymethane, formaldehyde, etc.…”

Selective excitations of a Kerr-nonlinear resonator: exactly solvable approach

“…The strong photon-photon correlation in this scheme is attributed by the destructive quantum interference between distinct driven-dissipative pathways [20,21]. Based on this mechanism, many different systems are proposed to realize the unconventional photon-blockade [22][23][24][25][26][27][28][29], moreover three oscillatory mode systems have also been considered [30].…”
