We have observed 2.6 mm CO J=1−0 emission in a complete sample of galaxies with starburst nuclei using the 14 m millimeter telescope of the Five College Radio Astronomy Observatory (HPBW=45″). The galaxies in this sample have distances between 15 and 40 Mpc, and central 10 μm luminosities (R < 500 pc) comparable to the starburst galaxy M82 (Devereux 1989). Molecular gas was detected in 16 of the 18 galaxies observed, with global H2 masses in the range 109 to 2.5×1010M⊙.
