a1-1 a1-1 a2-1 b2-1 800 nm E s&p model of molecular-anion photodetachment CHE-0134631 Electron wave dynamics using CS2- as model system Andrei Sanov, University of Arizona CS2- photoelectron images(Abel inverted) Detachment from the a1 HOMO in different orientations yields s and parallelp partial waves  parallel photoelectron anisotropy Detachment from the a2 MO in different orientations yields perpendicular p and nos partial waves  sharply perpendicular photoelectron anisotropy Detachment from the b2 MO in different orientations yields s and perpendicular p partial waves  slightly perpendicular anisotropy 400 nm Photodetachment from different CS2- MOs (a1 HOMO, b2 HOMO-1, and a2 HOMO-2) is considered for three principal orientations of the anion with respect to vertically polarized laser field. For each orientation/MO, the electric-dipole selection rule dictates the symmetry of the photodetached electron wave (yf). yf is expanded in the s, p, d, f, etc. basis, but the consideration is limited to the s and p components only. The spatial properties of the symmetry-allowed s and p partial waves determine the anisotropy of the photoelectron bands in the images. The model case of CS2- is used as a reference for interpreting the results for complex cluster anion systems
