Limiting the value of the permanent electric dipole moment of the electron (eEDM) provides a sensitive probe of the Standard Model of particle physics and its extensions. In the NL-eEDM experiment, molecules with velocities of ~600 m/s pass through well-known E- and B-fields in which a sensitive spin precession measurement is performed. In this thesis, the optical setup of this experiment is discussed, and precise spectroscopy of the quantum states employed in the spin precession process is shown. Systematic biases from parameters such as laser frequency, polarisation and power are vital to control and measure. The discussion in this thesis includes the experimental techniques employed to extract an eEDM limit and quantify these possible systematic effects.
