Royal Society Discussion Meeting (Jan 16-17)

and a Satellite Meeting (Jan 18)

Physics, Chemistry, and Astronomy of H3+

Organized by T. R. Geballe, D. Gerlich, T. Oka and J. Tennyson

(B. J. McCall, Secretary)

This Discussion Meeting is a second attempt to assemble researchers from different fields in which H3+ plays a major role and to discuss the most fundamental molecular ion from a variety of perspectives. Talks from the 2000 meeting have been published in Phil. Trans. R. Soc. Lond. A (2000) 358, 2359-2559. The recent exciting developments related to H3+ and deuterated species make this discussion particularly timely. The discussions will include the following subjects:

  • New Spectroscopy of H3+ and Deuterated Species,
  • First Principles Calculation of H3+
  • Theory of the Triplet State and Asymptotic Vibrational States
  • New Experiment and Theory of Electron Recombination
  • Dissociation Dynamics and Thermalization
  • Laboratory Chemistry of H3+ and Deuterated Species
  • Nuclear Spin in Chemical Reactions
  • Observed Ubiquity of H3+ in Interstellar Space
  • Radio Observations of Interstellar H2D+ and HD2+
  • H3+ and its Isotopomers in Deuterium Fractionation
  • Hot and Diffuse Gas near the Galactic Center and Metastable H3+
  • H3+ and Isotopomers in Planets and Protoplanets
  • H3, H5+, H3+(H2)n clusters, H3-, and H3++
  • Second Circular
