The Faraday Division of the RSC invite you to participate in the 127th Faraday Discussion focusing on Non-Adiabatic Effects in Chemical Dynamics to be held at St Catherine's College, Oxford from Monday 5 - Wednesday 7 April 2004.

Electronically non-adiabatic transitions are central to a wide variety of rate processes, ranging from charge transfer collisions in the upper atmosphere and interstellar material to organic photochemistry. Even a relatively simple reaction such as that between H atoms and water to form OH is known to involve no less than five electronic energy surfaces and current advances in both theory and experiment promise to unravel the detailed state selected dynamics of such events. Electronically non-adiabatic processes play an important role in all transition metal chemistry and may be central to some biological processes such as the chemistry of haemoglobin. There is also considerable topical interest in elucidating observable consequences of the so called 'geometric phase' associated with circumnavigating conical interactions.

New and unpublished experimental and theoretical work will be presented in the following areas:

• Photochemical dynamics
• Fine structure and charge transfer processes
• Surface hopping
• Observable consequences of geometric phase
• Dissociative attachment
• Non-adiabatic processes in biology
• Application to cold atom collisions

Chairman, Faraday Discussion 127

Delegates will arrive on the morning of Monday 5 April 2004, and the discussion will start after lunch. There will be four discussion sessions in total and the meeting will end on Wednesday 7 April 2004 after lunch. There will be a poster session for submitted contributions on Monday evening and a conference banquet on Tuesday evening.

Professor Mark S Child (Oxford) (Chairman), Professor Gabriel G Balint-Kurti (Bristol) , Professor Lorenz S Cederbaum (Heidelberg), Dr David L Cooper (Liverpool), Professor Hanspeter Helm (Freiburg), Professor David Klug (Imperial College) and Professor Michael A Robb (Kings College London).
