Fig. 2.

Stretching and bending of field-dressed CS₂. Geometrical parameters of CS₂ are retrieved as a function of the electron returning energy. By fitting a constant line, we estimate a C-S bond length R_CS = 1.86 ± 0.23 Å and a S-C-S angle Φ_SCS = 104.0° ± 20.2°, which correspond to a strongly symmetrically stretched and bent neutral CS₂. Top Left shows the return time of the rescattered electrons. Right shows models with molecular orbitals for field-free (FF) neutral CS₂ in the ground electronic state, ${\stackrel{\sim }{\text{X}}}^1{\Sigma }_{\text{g}}^{+}$, and the LIED-measured field-dressed (FD) structure. The corresponding R_CS and Φ_SCS values for these two structures are indicated.
