The Stark spectra of $CH3OD$ and $CD3OH$ have been investigated in the far-infrared region using the DCN and $H2O$ lasers. The spectra were recorded at room temperature for both parallel and perpendicular polarizations using electric fields up to 60 000 V/cm. Several transitions have been observed with these laser lines. For $CD3OH$, the transitions $JK=145\leftarrow 136E2vt=1,JK=143\leftarrow 152A-vt=1$, and $JK=116\leftarrow 107E1vt=1$ have been identified with the $195\mu m$ line of the DCN laser. Zero-field frequencies for all assigned transitions will be reported.
