Abstract

In a previous article [J. Theor. Comput. Chem. 2010, 9, 435], all rovibrational bound states of HO2 were systematically computed, for all total angular momentum values J = 0–10. In the present work, this effort is extended to the largest possible total angular momentum, J ≤ 130 — pushing quantum dynamical calculations to their practical limits using massively parallel high-performance computing via the ScalIT suite of codes.

Notes

  • Part of a larger body of work on exact quantum dynamical calculations of rovibrational spectra at Texas Tech
  • Uses the ScalIT parallel computing framework developed with Bill Poirier
  • HO2 (hydroperoxyl radical) is atmospherically relevant and notoriously difficult due to its open-shell nature
