There is a scientific discussion meeting to be held at the Royal Society on 21–22 January 2018, organised by Professor Jonathan Tennyson FRS, Professor Benjamin McCall, and Professor Steven Miller. The webpage for the meeting is available on the Royal Society's website.
This meeting will highlight recent developments in theoretical, laboratory and astronomical studies of the molecular ion H3+ and its hydrogenated cousin H5+. These developments include the first models of H5+, high-resolution studies of H3+ deuterated isotopologues, ultra-cold chemistry studies, new chemical models of the Galactic Centre, and data from the space missions Cassini (Saturn) and JUNO (Jupiter).
