Machine learning prediction of state-to-state rate constants for astrochemistry 
Auteur(s): Bossion D., Nyman Gunnar, Scribano Y.
(Article) Publié:
Artificial Intelligence Chemistry, vol. 2 p.100052 (2024)
DOI: 10.1016/j.aichem.2024.100052
Résumé: We investigate the possibility to use an artificial neural network in order to generate a large number of accurate state-to-state rate constants, from the available rates obtained at different accuracy levels, including small numbers of accurate rates and large numbers of low-accuracy rates.

Theoretical investigation of the H + HD $\rightarrow$ D + H$_2$ chemical reaction for astrophysical applications : a state-to-state quasi-classical study 
Auteur(s): Bossion D., Ndengué Steve, Meyer H. d., Gatti Fabien, Scribano Y.
(Article) Publié:
Journal Of Chemical Physics, vol. 153 p.081102 (2020)
DOI: 10.1063/5.0017697
Résumé: We report a large set of state-to-state rate constants for the H + HD reactive collision, using Quasi-Classical Trajectory (QCT) simulations on the accurate H$_3$ global potential energy surface of Mielke {\it et al.} [J. Chem. Phys. \textbf{116}, 4142 (2002)]. High relative collision energies (up to $\approx 56,000$~K) and high rovibrational levels of HD (up to $\approx 50,000$~K), relevant to various non thermal equilibrium astrophysical media, are considered. We have validated the accuracy of our QCT calculations with a new efficient adaptation of the MCTDH method to compute the reaction probability of a specific reactive channel.
