Rotationally inelastic collisions of Li2(A 1Σ+u) with Ne: Fully ab initio cross sections and comparison with experiment
TL;DR: The potential energy surface (PES) for the interaction of Li2(A 1 Σ+u) with Ne has been computed using highly correlated multiconfiguration-reference configuration expansions (MRCI) and a large basis set from the calculated points an analytical fit of the potential was obtained.

Dependence of level‐resolved energy transfer on initial vibrational level in Li2A1Σu+−Ne collisions
TL;DR: In this article, collision induced rotational and vibrational energy transfer was investigated under single-collision conditions at an effective temperature of 691 K. The experimental results were compared with their three-dimensional trajectory calculations on an ab initio potential surface and on a simple repulsive potential surface.

Hard shape potentials from rotational state‐to‐state inelastic cross sections: A possible route to inversion
S. Danko Bosanac,John N. Murrell +1 more
TL;DR: In this paper, a two-parameter hard shape potential has been deduced which reproduces previously reported rotationally inelastic integral cross sections for He-HF collisions, and is optimized to the 0→1 and 0→2 cross sections at a collision energy of 41.4 meV.

Rovibrational Energy Transfer in Ne−Li2(A1Σu+,v=0): Comparison of Experimental Data and Results from Classical and Quantum Calculations†
TL;DR: Analysis of classical trajectories indicates that the vibrationally inelastic collisions fall into two groups corresponding to equatorial and near-end impacts; the former generally produce small Deltaj while the latter produce large Deltj.

Rotational Energy Transfer in Highly Excited States of Lithium Dimer: Experiment and Modeling.
TL;DR: Level-resolved rate coefficients for collision-induced rotational energy transfer in the Li2* - Ne system suggest that the E and F states are much more nearly isotropic than the A state, and may be relevant in the relaxation of gases at high temperatures.

Jeremy M. Hutson,Brian J. Howard +1 more
TL;DR: Anisotropic potential energy surfaces for Ar · HC1 were obtained by simultaneous least squares fitting to molecular beam spectra, rotational line broadening cross sections, second virial coefficients and molecular beam total differential cross sections as discussed by the authors.
