a CF4 molecule and definition of the different quantities in the molecular frame. The direction of emission of the CF\({}_{3}^{+}\) ion defines the z-axis (blue arrow), which identifies the recoil frame in this experiment. The x-axis is contained in the plane identified by two fluorine atoms (1 and 2 in the figure). The orientation of the polarisation vector of the electric field (magenta arrow) is defined in the molecular frame by the angles α and β. The emission direction of the photoelectron in the molecular frame (cyan arrow) is defined by the angles θ and φ. RABBITT traces obtained for the parallel (0∘ ≤ β ≤ 45∘ and 135∘ ≤ β ≤ 180∘) b and perpendicular (60∘ ≤ β ≤ 120∘) c configurations. The angles α and φ cannot be determined in our measurements.
