Three negative-parity rotational bands have been identified in the 194Tl [1-3] nucleus. All three bands are associated with a four-quasiparticle πh9/2 x νi13/2-3 configuration at high spins. Two of these bands show exceptionally close near-degeneracy in the excitation energies, and furthermore a close similarity in their other properties, e.g. alignments, B(M1)/B(E2) ratios, etc. . Based on these results the pair of four-quasiparticle negative-parity bands in 194Tl was interpreted as perhaps the best chiral pair found to date . The nature of the third πh9/2 x νi13/2-3 band, however, remains unclear. It was suggested , that this band could correspond to axially symmetric nuclear shape. As an alternative, the three bands could form a multiplet of chiral partners built on the same nucleon configuration . In this work we aim at studying further the nature of the three negative-parity bands. We used the experimental data on the lifetime measurements for these bands  and performed multi-particle-plus-triaxial rotor model (MPR)  calculations. These calculations were carried out for both triaxial (β2 = 0.15, γ = 40°) and axially symmetric nuclear shape. The results will be presented and discussed.
