Title: Rotating and vibrating symmetric top molecule RaOCH$_3$ in the fundamental $\mathcal{P}$, $\mathcal{T}$-violation searches
Authors: Anna Zakharova
Abstract summary: We study the influence of the rotations and vibrations of the symmetric top RaOCH$_3$ molecule on its effectiveness as a probe for the $mathcalP$ and $mathcalT$-violating effects. The results show larger deviation from the equilibrium values than in triatomic molecules.

Abstract: We study the influence of the rotations and vibrations of the symmetric top RaOCH$_3$ molecule on its effectiveness as a probe for the $\mathcal{P}$ and $\mathcal{T}$-violating effects, such as the electron electric dipole moment (eEDM) and the scalar-pseudoscalar electron-nucleon interaction (Ne-SPS). The corresponding enhancement parameters $E_{\rm eff}$ and $E_{\rm s}$ are computed for the ground and first excited rovibrational states with different values of the angular momentum component $K$. For the lowest $K$-doublet with $v_\perp=0$ and $K=1$ the values are $E_{\rm eff}=47.647\,\mathrm{GV/cm}$ and $E_{\rm s}=62.109\,\mathrm{kHz}$. The results show larger deviation from the equilibrium values than in triatomic molecules.
