Rotational bands in 110,112Ru and 108Mo have been investigated by means of \gamma –\gamma –\gamma and \gamma –\gamma (\theta ) coincidences of prompt \gamma rays emitted in the spontaneous fission of 252Cf. New \Delta I = 1 negative parity doublet bands are found. These bands in 110,112Ru and 108Mo have all the properties expected for chiral vibrations. Microscopic calculations that combine the TAC mean-field with random phase approximation support this interpretation.
