We have recorded the infrared absorption spectrum of pyrrole at 0.005 cm⁻¹spectral resolution using a Fourier transform interferometer. The rotational analysis of the symmetric out-of-plane C–H bend 22¹₀fundamental band at 722.132993(5) cm⁻¹was performed, allowing 6760 lines to be assigned. These lines were fitted simultaneously to literature data on ν₁[A. Mellouki, R. Georges, M. Herman, D. L. Snavely, and S. Leytner,Chem. Phys.220, 311–322 (1997)] and microwave lines [G. Wlodarczak, L. Martinache, J. Demaison, and B. P. Van Eijck,J. Mol. Spectrosc.127, 200–208 (1988)]. A set of rotation parameters was determined for the ground state in I^rand III^rrepresentations, together with vibration–rotation constants for thev₁
