HeH+Collisions with H2: Rotationally Inelastic Cross Sections and Rate Coefficients from Quantum Dynamics at Interstellar Temperatures
(American Chemical Society, 2022-04-01)
We report for the first time an accurate ab initio potential energy surface for the HeH+-H2system in four dimensions (4D) treating both diatomic species as rigid rotors. The computed ab initio potential energy point values ...
Rotational state-changes in C5N? by collisions with He and H2
(Oxford University Press, 2023-04-28)
The anion C5N? is one of the largest linear (C, N)-bearing chains detected in the interstellar medium. Here we present and discuss the general features of new ab initio potential energy surfaces describing the interaction ...
