High resolution studies have been carried out on the $22,1-22,0$ transition of the HDS molecule, which occurs at about 11,284 Mc. A beam maser spectrometer, analogous to the original $NH2$ maser, was employed. Analysis of the hyperfine components affords a determination of the guadrupole coupling constant of the deuteron, as well as the spin-rotation constants, of the form $I\cdot J$
