Abstract :Some rotational components have been measured in the ground, the n 9 = 1 and the n 10 = 2 vibrational states for 13CH3CCH isotopic species in the frequency range 16--50 GHz. A set of rotational constants has been determined, which gives the best fit between the observed and the calculated frequencies, for each vibrational state. A Fermi resonance was found between these two states.
