Molecular physics and astrophysics group



"The underlying physical laws necessary for the mathematical theory for a large part of physics and the whole of chemistry are thus completely known and the difficulty is only that the exact application of these laws lead to equations much too complicated to be soluble."  
P.A.M. Dirac (1929)  

Atmosperic models 

Modern computers mean that it is now possible to solve many problems in the physics of small molecules. The group addresses fundamental problems such as:
Spectroscopy  H_{2}O (v,J) + hv  H_{2}O (v^{*},J^{*})  
Photodissociation  H_{3}^{+} + hv  H_{2} + H^{+}  
Photoionization  H_{2} + hv  H_{2}^{+} + e^{}  
Electron scattering  H_{2}^{+} + e^{}  H_{2}^{+} + e^{}  
Positron scattering  H_{2} + e^{+}  H_{2} + e^{+}  
Electron impact excitation  H_{2} + e^{}  H_{2}^{*} + e^{}  
Dissociative recombination  HeH^{+} + e^{}  He + H  
Where * denotes excitation. 
paying particular attention to those processes for which information is
urgently required.
To do this we often use the latest supercomputers
and develop appropriate algorithms. The group is involved in:
