The Cover Feature shows the structure of coumarin, a natural substance with the specific scent of maibowle. The microwave‐determined bond lengths and bond angles reflect pertubations of the π electron delocalization in coumarin. The large, negative inertial defect indicates pronounced out‐of‐plane motions of the ring. More information can be found in the Article by H. V. L. Nguyen and J.‐U. Grabow.
