The microwave spectra of cyclobutanone and of three isotopically substituted cyclobutanone molecules have been measured and the rotational constants determined. From the observation of the Stark effect it could be concluded that the four‐membered carbon ring must be planar. Further it was possible to calculate the structure of cyclobutanone from the moments of inertia, with only one arbitrary assumption. Stark effect measurements yielded a value of 2,98 D for the dipole moment of cyclobutanone.
