Much of our intuition about strong-field processes is built upon studies of diatomic molecules which have electronic states that are relatively well separated in energy. In polyatomic molecules, however, the electronic states are closer together, leading to more complex dynamics. We investigate experimentally and theoretically the strong-field ionization followed by hydrogen elimination for the hydrocarbon series C2D2, C2D4, and C2D6. Our findings suggest that one has to take into account the shape of the field dressed orbitals rather than the field free orbitals in order to interpret the experimental measurements. The Rydberg character contribution to these field dressed orbitals in strong-field ionization has to be considered to explain the photofragment angular distribution. This improved understanding can facilitate efforts at image-based strong-field coherent control.
