PCCP Physical Chemistry Chemical Physics

Cover See A. Sanov and W. C. Lineberger, pp. 2018–2032. Artist’s view of the s&p model treatment of negative-ion photodetachment. The electron waves shown are responsible for the angular anisotropy of the photoelectron images, which are depicted as islands floating among the water waves. The third of the three photoelectron images (islands) corresponds to 400 nm photodetachment of S2, while the first and second are obtained in 800 and 267 nm detachment from CS2, respectively. The molecular orbitals (shown in different lab-frame orientations) on the right are the a1 HOMO, b2 (HOMO  1) and a2 (HOMO  2) of the anion. The s and p orbitals on the left represent the s&p-wave expansion of the free (photodetached) electron formed via the a11, b21, and a21 photodetachment channels (laser polarization is assumed to be vertical). The corresponding photodetachment bands can be seen in the middle photoelectron image below. Image kindly supplied by A. Sanov, Department of Chemistry, University of Arizona, Tucson, AZ, USA.
