Abstract: The high-resolution (ca. 0.008 cm-1) stimulated Raman spectrum of the strongly perturbed C-H symmetric stretching region of (C2H6)-C-12 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.
