  Silicon dioxide (SiO$_2$) is expected to occur in the atmospheres of hot
rocky super-Earth exoplanets but a lack of spectroscopic data is hampering its
possible detection. Here, we present the first, comprehensive molecular line
list for SiO$_2$. The line list, named OYT3, covers the wavenumber range
0\,--\,6000~cm$^{-1}$ (wavelengths $\lambda > 1.67$~$\mu$m) and is suitable for
temperatures up to $T=3000$~K. Almost 33 billion transitions involving 5.69
million rotation-vibration states with rotational excitation up to $J=255$ have
been computed using robust first-principles methodologies. The OYT3 line list
is available from the ExoMol database at http://www.exomol.com.
