TL;DR: In this article, cross section data are compiled from the literature for electron collisions with methane (CH4) molecules and cross sections are collected and reviewed for total scattering, elastic scattering, momentum transfer, excitations of rotational and vibrational states, dissociation, ionization, and dissociative attachment.

TL;DR: In this article, theoretical calculations of complete sets of vibrationally state-resolved cross sections and rate coefficients are reviewed, focusing on the relevant classes of collisional processes: resonant and non-resonant electron-impact excitation of molecules, atom-diatom and molecule-molecule collisions as well as gas-surface interaction.

TL;DR: In this article, the authors present rotation-vibrational levels of water up to the dissociation limit using two recent, global potential energy surfaces using PDVR3D, which runs on computers with massively parallel processors.

TL;DR: The National Aeronautics and Space Administration (NASA) Infrared Telescope Facility was used to investigate the collision of comet Shoemaker-Levy 9 with Jupiter from 12 July to 7 August 1994.

TL;DR: In this article, a new, accurate, global, mass-independent, first-principles potential energy surface (PES) is presented for the ground electronic state of the water molecule, based on 2200 energy points computed at the allelectron aug-cc-pCV6Z IC-MRCI(8,2) level of electronic structure theory.
