The $R-(0)$ and $R-(1)$ lines of the $\nu 3$ band for the three isotopic silane molecules $\mathrm{<mrow\; data-mjx-texclass="ORD">28</mrow>}SiH4$, $\mathrm{<mrow\; data-mjx-texclass="ORD">29</mrow>}SiH4$ and $\mathrm{<mrow\; data-mjx-texclass="ORD">30</mrow>}SiH4$ have been recorded at high resolution in the infrared. The equivalent widths and absolute line strengths have been determined in a manner analogous to previous work from our laboratory on $germane1$ and $methane.2$ The transition dipole moments for the three molecules have been determined.
