Here, the structure of decoupled positive-parity and semidecoupled negative-parity bands up to high spin in 197,199Hg has been studied using multinucleon transfer reactions with the Gammasphere array. A positive-parity band in 199Hg with the (vi13/2)3 decoupled configuration that deexcites to levels in the negative-parity sequences is newly established. The semidecoupled sequences in both isotopes are extended to higher spin. Rotation-aligned angular momenta and crossing frequencies determined from experiment are in fair agreement with those from cranking calculations. Finally, a transition from oblate collective rotation at low spin to triaxial noncollective shapes at high spin is indicated.
