Royal Society Discussion Meeting

Astronomy, Physics And Chemistry Of H₃⁺

Organized by E. Herbst, S. Miller, T. Oka and J.K.G. Watson

This Discussion Meeting was a new 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. Recent discoveries of H₃⁺ both in molecular clouds and in the diffuse interstellar medium made this discussion meeting particularly timely.

This meeting was accompanied by a one-day meeting entitled "Molecules and Dust in Regions of High Excitation" on February 8th at University College London organized by D.A. Williams, D. Clary, and J. Tennyson, as well as a one-day meeting entitled "H₃⁺ Further Developments and Future Directions" on the 11th, also at University College London, organized by us. All interested attendees of the Royal Society Meeting were welcome at both of these meetings.
