Journal ArticleDOI
Calculated photoionization cross sections using Quantemol-N
Will J. Brigg,Alex G. Harvey,Anna Dzarasova,Sebastian Mohr,Danilo S. Brambila,Felipe Morales,Olga Smirnova,Jonathan Tennyson +7 more
TL;DR: In this article, an extension of the UK Molecular R-matrix code (UKRMol) for photoionization of molecular nitrogen and methane is presented. But this extension is designed for electron?molecule collision problems, and it is not suitable for the case of photoionized molecules.
Journal ArticleDOI
Effects of the potential anisotropy on the calculated fine-structure spectrum of O2He
TL;DR: In this paper, Ro-vibrational spin calculations were performed on the O 2 He van der Waals molecule using a recent emphical potential energy surface, and all the bound states of the complex were presented, as well as the fine-structure spectrum and weak-field Zeeman splittings of the low-lying states.
Journal ArticleDOI
Electron-impact rotational excitation of H3+: relevance for thermalization and dissociation dynamics.
TL;DR: Using the molecular R-matrix method combined with the adiabatic-nuclei-rotation approximation, new rate coefficients are computed for the rotational excitation of by electrons at temperatures from 10 to 10 000 K.
Journal ArticleDOI
First-principles calculations on the astrochemistry and spectroscopy of H+3
TL;DR: In this paper, a series of ro-vibrational calculations of spectroscopic accuracy using a high-quality potential-energy surface due to Meyer, Botschwina and Burton were performed.
Journal ArticleDOI
Water line intensities in the near-infrared and visible
R. N. Tolchenov,Mizuho Tanaka,Jonathan Tennyson,Nikolai F. Zobov,Nikolai F. Zobov,Sergei V. Shirin,Sergei V. Shirin,Oleg L. Polyansky,Oleg L. Polyansky,A. N. Maurellis +9 more
TL;DR: In this article, the ESA-WVR linelist is re-analyzed with a focus on effects due to pressure determination in the cell, subtraction of the baseline and parameterization of the line profiles.
