The vibrational spectrum of dimethylcyanamide has been reinvestigated. Two deuterium substituted isotopes, previously unreported, have also been investigated. The gaseous, liquid, and solid phase infrared spectra of all three compounds are reported for the region 4000 $cm-1$ to 33 $cm-1$. In addition, the Raman spectrum of each compound has been observed. Assignments of fundamental vibrational modes are proposed and torsional barriers calculated.
