Symmetry dependent P 1s excitation spectra of SPF3
have been obtained by performing photoelectron-photoion coincidence measurments
with the ion detector oriented both parallel and perpendicular to the electric
field vector of the exciting linearly polarized synchrotron radiation.
The resulting total ion yield spectra and most of the partial fragment
ion yield spectra show almost no polarization dependence. In contrast the
S+ and S2+
partial ion yield spectra do show a strong anisortopy, thereby providing
clear evidence for the symmetries of the core-excited states and demonstrating
applicability of the axial recoil approximation to a larger molecule than
has been considered previously. 1999 Elsevier Science B.V.
