| 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 areμtot =μb =2.9345(22) D for acetone from measurements on the 111← 101 transition, andμa =0.8631(8),μb =1.4345(11),μtot =1.6741(10) D for acetic acid, from measurements on 111← 000 and 101←000 transitions. A comparison with previous determinations and with results of quantum chemical calculations is presented. |
