Selected positions in the massive molecular cloud associated with the H II region Sharpless 252 have been studied by means of 12CO, 13CO, C18O, NH3(1,1), (2,2) and HCO+ molecular line measurements. Two local maxima lying only 2' apart were found in the molecular cloud core. The excitation conditions and radial velocities associated with the maxima are different. A strong HCO+ line reversal is observed in the cloud core.
