Query: Rovibrational structure of the Ytterbium monohydroxide molecule and the
  $\mathcal{P}$,$\mathcal{T}$-violation searches   The spectrum of triatomic molecules with close rovibrational opposite parity
levels is sensitive to the $\mathcal{P}$,$\mathcal{T}$-odd effects. This makes
them a convenient platform for the experimental search of a new physics. Among
the promising candidates one may distinguish the YbOH as a non-radioactive
compound with a heavy atom. The energy gap between levels of opposite parity,
$l$-doubling, is of a great interest as it determines the electric field
strength required for the full polarization of the molecule. Likewise, the
influence of the bending and stretching modes on the sensitivities to the
$\mathcal{P}$,$\mathcal{T}$-violation requires a thorough investigation since
the measurement would be performed on the excited vibrational states. This
motivates us to obtain the rovibrational nuclear wavefunctions, taking into
account the anharmonicity of the potential. As a result, we get the values of
the $E_{\rm eff}$ and $E_s$ for the lowest excited vibrational state and
determine the $l$-doubling
