The vibration-rotation spectrum of CH3I in the 2020-2440 cm-1 region consists of the absorption of the perpendicular system v2 + v6(E), v5 + v6(E), v3 + 2v6(E). The last two bands form a strongly coupled Fermi dyad with crossing at K' = 4 in the (+l) stack of levels. Evidence has been found for a z-axis Coriolis-type contribution to their matrix elements, linear in K and with opposite signs in the (+l) and (-l) series. The x - y Coriolis interaction of v2 + v6(E) with all components of v5 + v6(A1 + A2 + E) occurs as usual in methyl halides. The spectrum does not exhibit any direct absorption to the parallel system v5 + v6(A1 + A2), v3 + 2v6(A1) and v2 + 2v3(A1), whose presence is revealed by extensive perturbations of the perpendicular v5 + v6, v3 + 2v6 system, mostly by l(2, -1) interactions, generating anomalous rotational patterns in a wide K''ΔK range. Accurate values of the vibration-rotation parameters of the perpendicular bands were determined by a proper use of the available data. |
