Figure Lengend Snippet: EDDM for the S 1 → S 3 transition of the S 1 -LE structure, calculated with the use of the (a) XMS-CASPT2 and (b) SOS-CC2 methods. The EDDM is plotted in form of isosurfaces with isovalues of ±0.0025 e / a 0 3 . The red and blue isosurfaces delimit regions in which the electron density is, respectively, increased and decreased upon S 1 → S 3 vertical excitation.
Article Snippet: In Turbomole, such a calculation is only implemented for the coupled cluster singles (CCS) and the second-order approximate coupled cluster singles and doubles (CC2) methods.
