We report full-dimensional accurate quantum dynamical calculations of the rotationally
inelastic collision: para-H2 (1 0, j1 0) para-H2 (2 0, j2 0)→ para-H2 (1 0, j1) para-H2 (2 0, j2) …

As the most abundant molecule in the universe, collisions involving H2 have important
implications in astrochemistry. Collisions between hydrogen molecules also represent a …

A novel scheme is suggested to construct a global potential energy surface by switching
between representations which are optimal for different energy regimes. The idea is …
