Scientific paper

The stellar cluster and the massive molecular cloud associated with the H II region Sharpless 252 have been studied by means of multicolour polarization and molecular line measurements. The average wavelength of the maximum polarization λmax and polarization efficiency for the cluster stars are similar to the values observed for the nearby field stars. Two local maxima lying only 2arcmin apart were found in the molecular cloud core in CO, NH3, and HCO+. The excitation conditions and radial velocities associated with the maxima are different.
