dc.description.abstractThe internal rotation of the methyl group in methylpyrrole is hindered by a substantial sixfold barrier. The influence of complexation with argon on the barrier of methylpyrrole will be discussed. Rotational spectra of methylpyrrole-argon and methylpyrrole-$(argon)_{2}$ have been measured and the internal rotations splittings have been analyzed. The complexation of methylpyrrole with one argon atom reduces the symmetry of the internal rotation potential as the position of the argon atom is above the ring plane like in the pyrrole-argon complex. Only one parameter of the internal rotation potential was available from the observed splittings. A sixfold barrier is obtained again for methylpyrrole-$(argon)_{2}$ for which the two argon atoms are located symmetrically above and below the ring plane. The sixfold barrier was found to be slightly lower than that of methylpyrrole. In addition, the rotational spectrum of methylpyrrole with a partially deuterated methyl group has been measured. Two states of the internal rotation have been observed so far.en_US
