| contents | The sensitivity of experiments searching for the electron electric dipole moment (eEDM) using the symmetric top molecules can be greatly enhanced by laser cooling. A detailed understanding of the Zeeman structure of the eEDM-sensitive levels is crucial for controlling systematic effects.
We have developed a method for calculating the $g$-factors of $K$-doublet levels in symmetric top molecules and applied it to RaOCH$_3$. The electric-field-dependent $g$-factors of the first excited rotational level of RaOCH$_3$ are calculated. $K$-doublet levels with a small difference in $g$-factors are identified, and the main contributions to this difference are determined. |
