Results are reported from a search for methanol maser emission in the 12.2-GHz 2(0)-3(-1) E transition toward a sample of newly discovered 1665-MHz OH masers associated with IRAS FIR sources. Six methanol maser sources associated with H II regions were detected with a success rate similar to previous surveys of star-formation regions. The association of CH3OH and OH masers is briefly discussed. A strong correlation between the radio and FIR flux densities appears to favor a radiative pumping mechanism for the CH3OH masers. 17 references.
