The pure rotational spectrum of the free radical MgCH3( X tilde 2A1) has been measured in the laboratory for the first time using millimeter/submillimeter direct absorption spectroscopy. The molecule was made in a DC discharge by the reaction of magnesium vapor and dimethyl mercury. Ten rotational transitions of this species were observed in the range 176--374 GHz. MgCH3 is a symmetric top molecule with net spin angular momentum. Consequently, both K structure and spin-rotation interactions were observed in every rotational transition. The data were analyzed with a 2A1 Hamiltonian and rotational, centrifugal distortion, and fine-structure parameters were accurately determined. These measurements will now enable a search for this radical in interstellar and circumstellar sources to be conducted using millimeter/submillimeter telescopes.
