Summary on Grant Application Form
The aim is to move beyond the studies that we have already performed in S states of three-body systems (see Hazel Cox, PE Sinclair, SJ Smith and BT Sutcliffe, Molec. Phys. 87, 399-406 (1996) and reference therein) to P and D states. We should like to achieve this end while continuing to describe the system in perimetric coordinates so as to maximise the analytic simplifications that arise here. It may, of course, prove not possible to do this and certainly so far a way of doing it has not been found. However, in our previous work together the proposed visitor and I began to develop an alternative approach using Hylleraas coordinates which looks quite promising.In the long run, (but not in this proposal), we aim to study the Born-Oppenheimer separation between the various modes of motion in a molecule as a function if the constituent particle masses. We have made some such studies on S states already, but from those we can learn nothing about rotational motion. The work proposed here is an essential precursor to further studies.
