We report the microwave rotational spectrum of 2-bicyclo<3.1.0.>hexanone in its vibrational ground state and in vibrationally excited states associared with the bending mode ν_B of the five-membered ring.Variation of the rotational constants with v_b allows the conclusion that five/membered ring is effectively planar although the mode v_b is governed by an asssymetric potential energy function.Measurement of the Stark effect in a number of transitions leads to the components μ_a=3.28+/-0.02D and μ_b=1.81+/-0.2D of the electric dipole moment.
