Abstract Theoretical calculations are performed for neutron deficient Pt isotopes 177Pt and 175,173,171Pt in the particle-triaxial-rotor model with variable moment of inertia. The obtained energy spectra agree with experimental data quite well. The calculated results indicate that all these nuclei are in triaxial rotation with 177Pt being in prolate and 175,173,171Pt in oblate. Several levels are predicted for the 13/2+ band in 169Pt.
