Analysis of hot D2O emission using spectroscopically determined potentials.
Sergei V. Shirin,Nikolai F. Zobov,Oleg L. Polyansky,Jonathan Tennyson,Treana Parekunnel,Peter F. Bernath +5 more
TL;DR: Fourier transform emission spectra of D2O vapor were recorded at a temperature of 1500 degrees C in the wavenumber range 380-1880 cm(-1) and the spectrum was analyzed using variational nuclear motion calculations based on spectroscopically determined potential-energy surfaces.
Journal ArticleDOI
Differential cross sections for near-threshold electron impact dissociation of molecular hydrogen
TL;DR: In this paper, the major pathway for the electron impact dissociation of H2 is through excitation to b 3 + + +, and the formal expressions needed for such calculations, which involve three fragments in the exit channel, are derived.
Journal ArticleDOI
On the use of pseudostates to calculate molecular polarizabilities
Marc Jones,Jonathan Tennyson +1 more
TL;DR: In this paper, the pseudostates are represented by even-tempered expansions of Gaussian-type orbitals at the molecular centre-of-mass, and the method is tested for LiH, Li2, water and CO molecules.
Journal ArticleDOI
Quantum mechanics of highly excited states of the H+3 molecular ion: A numerical study of the two degree of freedom C2v subspace
TL;DR: In this article, two degrees of freedom quantum mechanical calculations on the bound states of H+3 photodissociation spectrum are presented, and the effect of rotational excitation is analyzed.
Journal ArticleDOI
Non-equilibrium H2 Formation in the Early Universe: Energy Exchanges, Rate Coefficients, and Spectral Distortions
Carla Maria Coppola,Carla Maria Coppola,R. D'Introno,Daniele Galli,Jonathan Tennyson,Savino Longo +5 more
TL;DR: In this article, the effects of a non-thermal distribution of the level populations of H2 in the early universe have been investigated in cosmological simulations of the evolution of baryons, and new fits to the equilibrium and non-equilibrium heat transfer functions are provided.
