The infrared spectrum of $CH3SiHD2$ has been investigated in the region $2000-5000cm-1$ with a resolution of $0.2cm-1$. Fourteen bands were observed, but only four were resolved sufficiently to enable an analysis to be performed. Three of these four bands, occurring at $2165cm-1,2982cm-1$, and $4262cm-1$, are type C. The band which occurs at $2835cm-1$ is type A. The band at $2165cm-1$ contains more rotational fine structure than any of the other three bands. The anaalysis of this band yielded $A\prime \prime =1.327cm-1\pm 0.002cm-1$. Values have been obtained for $A1B1C1,DJ,DJK,DK$, and the band origins of the four resolved bands. Approximate band origins have been obtained for many of the other bands observed in this study.
