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 J_K = 14₅~ ~13₆~E₂~ _t~=~1, J_K = 14₃~ ~15₂~A^-~ _t~=~1, and J_K = 11₆~ ~10₇~E₁~ _t~=~1 have been identified with the 195 µm line of the DCN laser. Zero-field frequencies for all assigned transitions will be reported.
