AbstractWe present interferometric observations of the W51 region at 2.7 mm and 3.3 mm with the Berkeley-Illinois-Maryland Association Array. The lines of CH3CN (J = 6 - 5, K = 0, 1,2,3,4), CH3OH (15(-2) - 15(1), E), HCOOCH3-A (7(1,6) - 6(1,5)), HCOOCH3-E (7(1,6) - 6(1,5)) and (CS)-C-13 (2- 1) as well as the 2.7 mm continuum toward W51 have been observed. The derived total beam-averaged column densities N-T and fractional abundances of CH3CN, CH3OH, HCOOCH3 and (CS)-C-13 in W51 cores have been obtained.
