The $\mathrm{<mrow\; data-mjx-texclass="ORD">14</mrow>}N$ species has been assigned and the $\mathrm{<mrow\; data-mjx-texclass="ORD">14</mrow>}N$ quadrupole coupling analyzed. The 15N species has also been assigned and its dipole moment determined. The Ar atom is located 3.56 A from the pyrrole center of mass and the Ar-center of mass line is tilted $5.8\circ$ from the normal to the pyrrole plane toward the N atom. The dipole moment of the complex, $1.7074(11)D$, is smaller than that of pyrrole. $1.7675(6)D$. From a pseudodiatomic centrifugal distortion analysis, the binding energy is $261(2)cm-1$.
