Vibrational excitation influence in a chemical laser based on polyatomic chemical reaction dynamics*

The author's research focuses on a polyatomic reaction in the gas phase, OH + D₂ ---> HOD + D. He uses Quasi-Classical Trajectory (QCT) methodology on Wu-Schatz-Lendvay-Fang-Harding (WSLFH) potential energy surface (PES) [1] because it is one of the best PES for this study. The amplitude of the samples, allows to obtain clarifying results that confirm previous researches [2] and show future experimental targets. Author uses Gaussian Binning (GB) methodology to show in a better way a variable preference in values of the Total Angular Momentum (J’) of excited product molecule, HOD*((v_HO’, v_HOD’, v_OD’), J’). One of his present intention is studying dynamics of this chemical reaction, because of its significance in the processes of excitation and emission in a posible chemical laser based on that reaction. The increase of the vibrational level, v , in one of the reactives, D₂ (v = 0, 1, 2, 3, 4; j = 2), induces a significative increase of the mentioned excitation, HOD*, and a displacement of the distributions, P(J'), towards higher values of J', but a greater dispersion of this distribution. Althought j = 2 is the initial condition is fixed in the present study, author pretends to amplie their researchs for a more amplie espectrum of posible initial conditions in the reaction camera.
