Summary on Grant Application Form |
|
An instrument will be developed which, by using fast response, imaging detectors, is able to identify the electron-ion pairs emanating from thephotoionization of individual molecules. From the velocity and direction observed in a large number of these events the energetics and angulardistributions of quantum state-selected ionization and dissociation processes can be found. The ability to observe angular distributions from what are,effectively, oriented molecules is particularly novel, but will reveal great detail about the anisotropic interactions of polarised photons with the molecule,and about the interaction of the departing electron-ion and ion-neutral fragment pairs. The symmetry of energetically degenerate continuum states canbe probed by these means and it is anticipated that new insights into the coupling of electronic and nuclear degrees of freedom can be obtained,including new 'symmetry breaking' phenomena. -The interaction of larger biomolecules with polarised ionizing light can also be examined, with onsideration to the needs of Food Scientists seeking better ways to analyse flavour on human breath samples. In particular, new physical theories concerning the differential response of chiral molecules with circularly polarised radiation can be examined, which may ultimately permit the rapid instrumental discrimination of optical isomers which are perceived by the human nose to have very different odours.
