The high‐resolution ( ca. 0.008 cm −1 ) stimulated Raman spectrum of the strongly perturbed CH symmetric stretching region of 12 C 2 H 6 at room temperature and at a rotational temperature of ca. 30 K, achieved in a free supersonic jet expansion chamber, is reported. The spectrum is tentatively analysed and assigned in terms of a simplified vibration‐torsion–rotation Hamiltonian. Besides the already known strong Fermi resonance, several Coriolis torsional interactions are identified as the major perturbations in this spectral region.
