Rotating and vibrating symmetric-top molecule RaOCH3 in fundamental P, T-violation searches

We study the influence of the rotations and vibrations of the symmetric-top RaOCH3 molecule on its effectiveness as a probe for the P, T-violating effects, such as the electron electric dipole moment and the scalar-pseudoscalar electron-nucleon interaction. The corresponding enhancement parameters E-eff and E-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(perpendicular to) = 0 and K = 1 the values are E-eff = 47.647 GV/cm and E-s = 62.109 kHz. The results show larger deviation from the equilibrium values than in triatomic molecules.
