Scientific paper

A survey of 27 galactic star-forming regions in the 6_K-5_K and 5_K-4_K CH_3CN lines at 110 and 92 GHz, respectively, was made. Twenty-five sources were detected at 110 GHz and nineteen at 92 GHz. The strongest CH_3CN emission arise in hot cores in the regions of massive star formation. CH_3CN abundance in these objects is increased up to 10-9 or larger. Weaker CH_3CN lines were found in a number of sources. They may arise in warm (30-50 K) clouds.
