Discussion meeting

Location

The Royal Society, London, 6-9 Carlton House Terrace, London, SW1Y 5AG

Overview

Scientific discussion meeting organised by Professor Jonathan Tennyson FRS, Professor Benjamin McCall, and Professor Steven Miller.

This meeting will highlight recent developments in theoretical, laboratory and astronomical studies of the molecular ion H3+and its hydrogenated cousin H5These 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).

The schedule of talks and speaker biographies are available below. Recorded audio of the presentations will be available on this page after the meeting has taken place.

Poster session

There will be a poster session at the end of the meeting on Monday 21 January. If you would like to apply to present a poster please submit your proposed title, abstract (not more than 200 words and in third person), author list, name of the proposed presenter and institution to the Scientific Programmes team as soon as possible. Please note that places are limited and posters are selected at the scientific organiser's discretion. Poster abstracts will only be considered if the presenter is registered to attend the meeting.

Attending the event

This meeting is intended for researchers in relevant fields.

  • Free to attend
  • Limited places, advanced registration is essential
  • An optional lunch can be purchased during registration

There will be a drinks reception at the end of the first day of the meeting (Monday 21 January 2019). The reception is free to attend for all registered participants and speakers and will take place at the same time as the poster session.
