A computer-controlled Hewlett-Packard microwave spectrometer has been used to record the lineshapes of OCS and $CH3OH$ transitions at several pressures in the microwave region. The widths of the $J=1\to 2$ transitions in $\mathrm{<mrow\; data-mjx-texclass="ORD">18</mrow>}OCS$, $O13CS$, $OC34S$, OCS ($v2=2$), and OCS ($v3=1$) have been compared to the width of the ground state transition of the parent under identical conditions. The widths of the M components of the $J=3\to 2,K=1\to 0$, E level transition to $CH3OH$ have been measured in a parallel plate absorption cell. The linewidth of the $J=4\to 3,K=0\to 1$, E level transition in $CH3OH$ has been determined both in absorption and dispersion.
