Magnetic quadrupole moment of ${}^{175}$Lu and parity-violating polarization degree of levels in ${}^{175}$LuOH${}^{+}$

The calculation of the parity-violating polarizations in the external electric field, which are associated with the electron electric dipole moment ($e$EDM) and magnetic quadrupole moment (MQM) of the ${}^{175}$Lu nucleus, as well as the determination of the rovibrational structure for the ${}^{175}$LuOH${}^{+}$ cation, is performed. Beyond the bending of the molecule, the slight effect of the stretching of the distance between Lu and OH is taken into account. This study is required for the preparation of the experiment and for the extraction of the $e$EDM and MQM values of ${}^{175}$Lu from future measurements.
