Abstract
We have used the IRAM Plateau de Bure Interferometer to observe the ground state and vibrationally excited lines of Methyl Cyanide towards the UCHII region G31.41+0.31. We also obtained a map of the continuum emission at a frequency of 110 GHz. We detect a hot molecular core in the emission both of methyl cyanide and of the 110 GHz continuum. We estimate a temperature of 200 K and a mass of 1000 Mo for this compact massive region. We also detect a velocity gradient or shift across the methyl cyanide core whose origin could be due to rotation.
