Abstract
We present the first variational calculation of a room temperature \textit{ab initio} line list for
the CH$_3$ radical. It is based on a high level {\it ab initio} potential energy surface and dipole
moment surface of CH$_3$ in the ground electronic state. The ro-vibrational energy levels and Einstein
$A$ coefficients were calculated using the general-molecule variational approach implemented in the computer program
TROVE. Vibrational energies and vibrational intensities are found to be in very good agreement with
the available experimental data.
