Abstract

The pure rotational spectrum of the SrCH₃ radical (Χ̃ ²Α₁) has been recorded using millimeter/sub-mm direct absorption techniques in the range 162-371 GHz. These data are the first high resolution measurements of this symmetric top species. The Κ = 0, 1, 2, and 3 components in each of seventeen rotational transitions of SrCH₃ were observed, including fine structure splittings. Rotational and spin-rotation parameters have been obtained for SrCH₃, and its structural and electronic properties are compared with those of other strontium radicals and metal monomethyl compounds. Substantial spin-orbit interactions appear to influence the fine structure splittings in these metal monomethyl species.
