Precise values for electric dipole moments of isolated acetone and acetic acid molecules were determined from the Stark effect measurements made on lowest J rotational transitions at conditions of supersonic expansion. The new results areμ_{tot} =μ_b =2.9345(22) D for acetone from measurements on the 1_{11}← 1_{01} transition, andμ_a =0.8631(8),μ_b =1.4345(11),μ_{tot} =1.6741(10) D for acetic acid, from measurements on 1_{11}← 0_{00} and 1_{01}←0_{00} transitions. A comparison with previous determinations and with results of quantum chemical calculations is presented.
