Surprisingly polar : The single‐sided scissoring‐induced sudden‐polarization effect in D 2 d ethene is first order (see picture). The important role of this coordinate was until now overlooked, although it was known for a long time that each geometrical distortion that leads to a breakage of the D 2 d symmetry results in a charge separation.
